Mega Man: The Wily Wars (Rockman Mega World in Japanese) is a Sega Mega Drive exclusive title released in Europe and Japan.
Basically serving as the Mega Man equivalent of Super Mario All-Stars, The Wily Wars contains 16-bit upgrades of Mega Man, Mega Man 2, and Mega Man 3. These remakes feature almost completely overhauled sprite work, remixed music, and a new save feature while staying as faithful to the design of the originals as possible. In addition, beating all three games unlocks a brand new game mode, Wily Tower, where Mega Man has to fight the Genesis Unit, consisting of three new Robot Masters built by Wily to defeat him, all while allowing the player to choose up to 8 weapons from all three of the original games to help him along the way.
As a Compilation Rerelease, there's no in-game story, though the manual provides a small framing device: After building himself a time machine, Dr. Wily travels back in time to Make Wrong What Once Went Right, with Mega Man himself being sent back by Dr. Light to relive his first three battles with Wily and stop his efforts to rewrite history.
While The Wily Wars was also available in U.S. and Canada, it only appeared as a brief Sega Channelnote exclusive with no physical release. The short availability window combined with the lack of re-releases made the game somewhat notoriously obscure to the North American audience, who had no good way to play it legally. The game would eventually return in 2019 via its inclusion in the Sega Genesis Mini console, and a physical cart would receive an official limited reprint in 2021.
Tropes exclusive to The Wily Wars remakes of the games:
- Anti-Frustration Features:
- The game comes with a save feature instead of a password system. Since unlocking Wily Tower requires beating all three included games, this is quite convenient.
- When standing still and trying to move slowly to the edge of a platform, there's a larger window than normal before Mega Man breaks into a run, making it slightly easier to line up tricky jumps (though this can lead to its own set of problems).
- Some of the more lackluster weapons were made slightly more usable; notably, the Top Spin's bugged ammo usage is fixed, and the Hyper Bomb detonates much more quickly.
- Art Evolution: The spritework for all three games is overhauled from the ground up for much more detail and richer color than what was possible on the NES.
- Compilation Rerelease: The cartridge contains remakes of the first three Mega Man games, with an unlockable new Wily Tower game mode added in as a bonus.
- Damn You, Muscle Memory!:
- For those used to the NES versions of the games, there are a few minor differences in the controls that can be hard to adjust to (on top of a bit more input delay). For instance, when Mega Man is at a standstill and the player starts pressing left or right, Mega Man will scoot forward for a frame or two before breaking into a run (in an effort to make it easier to "shimmy" to the edge of platforms), effectively adding extra delay to your movement.
- Specific to the remake of Mega Man 3, when coming out of a slide while holding left or right, Mega Man will stand still for a brief moment before continuing to move.
- Difficulty by Region: The remakes significantly bump up the already high difficulty of the games, and 2 no longer has its lower difficulty option. On top of that, the famous Pause Trick in the original game has been patched, meaning there's no shortcuts to beating Yellow Devil now.
- Excuse Plot: The manual does have a bit of extra backstory (Wily has used a time machine to go back and try to rewrite the events of the original games, and Mega Man has to stop him), but it's never brought up in-game. The backstory is otherwise a thinly-veiled excuse to kick Wily's butt three times over again while doubling as a cute reference to the games being remakes.
- Off-Model: Oddly, Proto Man of all characters does not get a new spriteset for 3, which simply recolors his NES sprites. Considering Mega Man's new sprite is now noticeably larger than in the original, this makes the contrast very jarring and hard to overlook.
- Shot-for-Shot Remake: The games are practically identical to the NES originals outside of the improved audio and visuals allowed by the stronger 16-bit hardware of the Mega Drive. The only other notable differences are a couple slight physics tweaks and the removal of some glitches.
- Updated Re-release: The collection serves as one to the first three NES Mega Man games.
Tropes pertaining to Wily Tower:
- Anti-Frustration Features: As Wily Tower lets the player mix and match weapons from Mega Man 1-3, none of the Wily stages force the player to use specific weapons or utilities to progress (though some sidepaths can be accessed with the right weapons). Additionally, every boss has multiple weaknesses rather than being weak to only one weapon.
- Call-Back: The Wily stages are exclusively populated with enemies and gimmicks from their respective game; Wily 1 only has enemies from Mega Man 1, Wily 2 only has enemies from Mega Man 2, and Wily 3 only has enemies from Mega Man 3.
- Damage-Sponge Boss: Unlike any Robot Master before or since, Hyper Storm H has two health bars instead of one, and mostly relies on using his Vacuum Mouth to push or pull Mega Man around, or summoning Mets.
- Design-It-Yourself Equipment: The player can equip a stack of weapons and utilities from all three of the original Mega Man games to use against Wily's Genesis Unit, mixing and matching as they see fit.
- Excuse Plot: The game's "plot" is little more than an excuse to fight three brand new Robot Masters while using all your favourite weapons from the first three games.
- Fiery Salamander: The boss of the first Wily Tower stage is Fire Snakey, a fire-themed variant of the Snakeys seen in Snake Man's stage.
- Humongous Mecha: The Wily Machine is so tall, the head is initially offscreen, and the first phase is merely against its legs.
- Meaningful Name: The Genesis Unit is a reference to the Sega Genesis, the console the game was made for. In Japanese, they're known as the Mega World Corps, after the Genesis's original Japanese name, the Mega Drive, and the Japanese name of The Wily Wars itself.
- Recurring Boss: Buster Rod G flees the battle against him in his stage, only to reappear as the boss of the third Wily stage (where he'll be defeated for good).
- Shout-Out: The Genesis Unit is clearly inspired by the characters from Journey to the West; Buster Rod G is based on Sun Wukong, Mega Water S is based on Sha Wujing, and Hyper Storm H is based on Zhu Bajie.
- Title 1: Weapons from the original Mega Man are listed as coming from "Mega Man 1" on the weapon selection screen.
- A Winner Is You: After beating the game, the ending merely consists of Mega Man chasing Wily beneath a roll call of the game's 25 Robot Masters, before he escapes and Mega Man jumps in the air.
