Lil Monster is an obscure Game Boy ColorRPG. Inspired by Pokemon, you make a monster beat up other monsters with a "deck" of attacks chosen at random, in the vein of Mega Man Battle Network.While the US saw only Li'l Monster, Japan had two entries in the franchise—this game, known as Gem Gem Monster there, and a prequel called Kandume Monster.
This game contains examples of:
Antidote Effect: Even though they're hard to get, Canaries are mostly useless.
Artificial Stupidity: Confuse your opponent right after you poison them? Deliberately putting bad gems in your deck? Sure! However, there are times when the CPU does do some pretty smart things...
Boss in Mook Clothing: The aptly-named Tricky, with its super-speed, powerfully damaging attacks, and lots of healing abilities.
Bragging Rights Reward: The StarChange gem renders all of your attacks super effective against enemies and gives you no weaknesses, but you only get it once you defeat the final boss.
Cain and Abel: Hot Joe (good) and Cool Joe (evil). Interestingly, Cool Joe is the younger one.
Combos: The "Combo" gem, which gets more powerful the more of them you have in your hand when you use it.
Continuing Is Painful: While continuing allows you to change your monster's species, it also halves their love for you, resets their weight, and makes you lose the gem you use.
Counter Attack: The Dream, Counter, and Reflect gems all do damage to your enemy when they attack you. Dream and Counter don't do as much damage as Reflect, but there are several powerful moves that can skirt Reflect.
Death Isnt Permanent: If your monster dies, you can just turn it into another one by using another gem.
Disc One Nuke: Minhand, which doubles your attack power. You can only get it if you you use Dowser's gem to summon the monster, however.
Elemental Rock-Paper-Scissors: Actually, it's card suit rock paper scissors. Spade beats Heart, Heart beats Club, Club beats Diamond, and Diamond beats Spade.
Guide Dang It: Many of the puzzles. Given that no complete strategy guide for this game seems to exist, even on the Internet, good luck! Many of the puzzles in this game involve using items in random places, though you'd never think of most of them—such as using the MiniCar in the first area of Mt. Coral to enter the MiniCar Grand Prix, or using the Battery in the second area of Aloe Lake to open the Fishing Mini Game. There lack of NPCs to help you along doesn't help...
Hello, Insert Name Here: Weirdly enough, even though you give your character a name, most NPCs will only refer to your monster.
Interface Screw: Several varieties. GemWave completely randomizes your hand, the Confusion status effect will keep you from choosing your moves, Bio and Combat transform your gems into ones that hurt you, and Virus slowly replaces all of your gems with itself, which causes 25 damage every time you use it.
In-Universe Game Clock: Li'l Monster has one, though the cycle is pretty long—it takes about 3 or 4 real-world hours of gameplay to trigger night. The game can be beaten in less time than that. Averted with Kandume, which used a real-time clock.
Killer Rabbit: Par for the course in a children's Mons game. Including literal, bright-purple rabbits!
Lost Forever: The Dowser and Dragonscale ability gems, and their associated monsters, Gyro and Argon. These two monsters are fought as bosses. However, the bosses will only appear once, and if you lose to them, they'll vanish. You'll never be able to get their ability gems.
To make things even more annoying, due to a variant on Tech Trees, failing to get Dowser will prevent you from getting the extremely useful Minhand, which doubles your attack.
Quad Damage: The Minhand gem, which doubles your attack, and the HiSpeed gem, which does the same for your speed.
Random Encounter: Notable for being a complete and total aversion—except for a few boss fights, you never even see enemies wandering the map! You choose not only when you'll fight, but what you'll fight.
Sequel First: The US-released Li'l Monster is actually a sequel to a Japan-only game called Kandume Monster.
Skippable Boss: You don't have to beat Gyro or Argon at all to advance the plot! But if you lose, you'll lose a pair of unique gems.
Useless Useful Spell: The Reflect gem. Although it's a powerful Counter Attack that will deal any damage dealt to you back at your enemy, there are several gems which it doesn't affect... two of which are the second-most-powerful gems in the game, and are found in the arsenals of most of the strongest enemies. However, it can be Not so useless against enemies that like to spam you with the most powerful gem, Meteor Drop.
