In an Adventure Game and a Role-Playing Game, you need to explore everywhere to find information or important items to help you on your mission. Townspeople are usually a good source of information and for leads on where to get such items. While questioning people on the streets or customers patronizing businesses are common, some heroes take it one step further and actually enter private houses in search of what they need. For some strange reason, many games don't have these homeowners reacting negatively to the protagonist just barging in. This seems to go against Real Life, where many jurisdictions have laws against trespassing. Even if there's no legal questions brought up, many consider it impolite to simply enter a home uninvited or at least with advance notice. For this trope to apply, the heroes have to enter an area that would normally be restricted to them such as a private residence, a secure facility, etc. Going into a public place (shop, restaurant, park, etc) or a facility with areas open to the public doesn't count. Compare Plot Armor. Compare and Contrast Hero Insurance. Also contrast Insurmountable Waist High Fence and Broken Bridge (which prevents you from going outside of the boundaries). If you go a step further, you get Kleptomaniac Hero, a sister trope.
- In The Battle For Endor of Star Wars: Ewok Adventures, Cindel and Wicket encounter a creature named Teek who takes them into an apparently empty house. Cindel and Wicket soon learn that the house does have an owner, who expels them when he returns.
- The first Back to the Future has Doc Brown and Marty simply walking into Hill Valley High School to locate Marty's future parents and fix the damage Marty unwittingly caused earlier. Nobody seems to say or do anything about these obvious trespassers in the school.
- Aragorn, Legolas and Gimli are viewed as being trespassers in Rohan around the start of "The Two Towers" in The Lord of the Rings (as well as in the movie), upon encountering Eomer and his patrol. This is justified as orcs are active in the lands and both of Aragorn's companions are obviously not native to Rohan.
- In "Flame of the Inquisition" from the Time Machine Series, if you made a wrong choice, you were arrested by knights during your travels for unknowingly trespassing on their duke's land.
- Uncle Traveling Matt of Fraggle Rock became a perfect example of this trope when exploring "Outer Space", the world of the "silly creatures" (humans). A number of postcard segments show Matt inside of office buildings, schools and even inside private houses. He observes people in kitchens, living rooms, and bedrooms and then reports it back to Gobo through postcards. Matt's intrusions into these homes makes you wonder if Fraggle society doesn't have established protocol on privacy and personal space.
- The Elder Scrolls II: Daggerfall allowed your character to enter locked houses if you wish by picking the lock or simply breaking the door down. This however would bring the guards.
- The other games in the Elder Scrolls series took away the option of breaking the door down but you could still pick the lock (or use an Unlock spell.) You'd have to be seen by a guard in order to get a bounty for doing this.
- Baldur's Gate has one of four things happen if you enter someone else's house in the big cities like Beregost and Baldur's Gate. The inhabitants may have a quest for you to do and completely ignore your trespass; may state clearly that they frown upon you barging in (but don't do anything); some call the guards on you; and some will even outright attack you.
- Lampshaded in Robopon when a townsman actually says "You can even go into someone's house without permission and take things!"
- Averted in King's Quest I: Quest For The Crown with Rumpelstilkin. After he helps you on your quest, he goes back inside his home. If you try to have Graham enter the home (at least in the official and fan remake), the game will call you out and say that it's impolite to enter someone's house uninvited.
- Subverted in the first Leisure Suit Larry game. Larry can walk into just about anywhere, but is barred from entering the dance club or the penthouse of the casino/hotel...unless he use the correct item.
- In Ultima VIII, the Avatar can't walk into houses that are locked unless you have lockpicks, find another way in or use explosives to blow open the door. Be warned that if you're caught, you will suffer terrible consequences for breaking and entering someone's house.
- The castle at Eginbear in Dragon Quest III requires your to trespass in order to gain a crucial item. The guards won't let you in; you'll need to use either the Invisibility Herb or Invisibility spell to get past the guards. For some reason, none of the castle's inhabitants seem to object to your presence inside.
- Bioshock Infinite. Several times during the game you can go into private residences and ransack the place without any repurcussions. In one case you can steal money and food from a house while the people are still in it and know you're there.
- Zig-zagged in Robotrek. In your character's new hometown of Rococo, when he approaches a house he rings the doorbell before the door opens for him. But the homeowners never object to him rummaging around their cabinets for items. Plus there are other places like the sewers where kids are expressly forbidden, yet his quest takes him there anyway. And then the houses in the tropical village have no doors, so there's nothing to keep him from walking in unannounced.
- In Dragon's Dogma, the Arisen has no qualms about going into people's homes in his hometown. Perhaps it's justified, as the Arisen was a fisherman before he was called to action, and most of the houses he randomly enters and steals greenwarish from are Fisherman's Houses.
- In Final Fantasy X, Tidus enters people's homes in every town he goes to. The people usually don't care and chat with him as if he's a guest. Even while Seymour's gone, Tidus still goes through his mansion if there are no guards about.
- Link from The Legend of Zelda. No one cares when he trots in, breaks peoples pots and steals their valuables. But at least one guy in the ENTIRE series questions this.
- The character in Animal Crossing is able to visit his neighbours by simply knocking before immediately barging in if they're present. In the first game, he could enter even if they weren't home, but now they must be there first.
- Lampshaded in Dink Smallwood mod Quel. When the local wizard objects to Dink walking into his home without an invitation the following exchange takes place.
Dink: I always walk into people's houses. It's what I do. Only it doesn't work up north for some reason. You've got to help me!
Wizard: You've got issues.
- A staple in all games of the Thief series.
- In chapter one of Spandex Force 2: Superhero U missing student Ms. Supreme attacks you for fighting with her father. When you object that he started it:
Infinitorax Supreme: Well, it might be a quaint concept, but I really don't approve of strangers invading my home!
- Lampshaded in Kingdoms Of Amalur Reckoning by a hermit named Derfel, who asks if waltzing into other people's houses uninvited ever ends poorly for you.
- Averted in Neverwinter Nights mod A Time for Heroes. If you break down a locked house door and enter, the irate occupants call for the guards, who will show up if you wait around long enough.
