Anything Mega Man, firstly (that covers games from at least the NES, SNES, PSX, CPS1 and CPS2, GBA, and the obscure DOS and GG ones).
That's my favourite game series of all time.
Adventure Island II, Kid Icarus, Darkwing Duck, Super Mario Bros. 1, 2, 2 (J), and 3, and Street Gangs (EU version of River City Ransom), all for the NES.
Super Mario World, Super Ghouls 'n' Ghosts, Kirby Super Deluxe (a.k.a., Kirby Super Star/Kirby's Fun Pak), Earthworm Jim 1 and 2, and Donkey Kong Country 2: Diddy's Kong Quest, all for the SNES. Also, Star Fox and Star Fox 2. Damn fine games - the "revised continuity" ones which wrote them out of existence, that began with Star Fox 64, simply cannot hold a candle to them, in my humble view.
Sleepwalker, Fire & Ice, Fantastic Dizzy, Pinball Dreams, Lemmings, and Little Computer People; Amiga.
Jazz Jackrabbit, Commander Keen: Invasion of the Vorticons and Goodbye Galaxy! (iD Software's only store offers both of these sets for $10, download-only, if anyone's after them
), and Skyroads, for MS-DOS.
Short Circuit, Pitfall! II: Lost Caverns, Park Patrol, Yogi's Great Escape, Scooby-Doo & Scrappy-Doo, Quick Draw McGraw, 3D Pinball - Pinball Power, and Rick Dangerous, for the C64.
Gargoyle's Quest, Metroid II: Return of Samus, and Super Mario Land, for the Game Boy.
Klonoa - Empire of Dreams -, Klonoa G2: Dream Champ Tournament, and Jazz Jackrabbit, for the Game Boy Advance.
The entire Rocket Knight Adventures series - Rocket Knight Adventures and Sparkster for the Mega Drive, and the completely different Sparkster for the SNES.
High Seas Havoc, a not-too-well-known Mega Drive platformer by Data East (known as "Capt'n Havoc" in Europe, and "Captain Lang" in Japan).
Strider!
Also, Ghouls 'n' Ghosts, Mega Twins, Three Wonders (Midnight Wanderers rules
), Super Street Fighter II Turbo, Final Fight, Captain Commando, Bubble Bobble, Bubble Symphony, The NewZealand Story (the earlier version, which was also ported to most home systems, rather than the later revision
), Liquid Kids, and Puzzle Bobble 2.
The three games in the rather obscure Kaizou Choujin Shubibinman series for the TG-16/PCE (the second game was translated as "Shockman", and was the only one released in English), plus the equally obscure spin-off BS Kaizou Choujin Shubibinman Zero (roughly the series' equivalent to Mega Man X) for the Super Famicom.
Alien Crush for the TG-16.
Klonoa - Door To Phantomile, Heart of Darkness, Namco Museum Vol. 5 (excellent because it has the only English-language release of The Legend of Valkyrie), Croc: Legend of the Gobbos, and Wild ARMs (this is an excellent RPG, and the only one I have ever found fun or engaging - highly recommended, if you can find it
), all for the PlayStation.
The above represents a sizeable chunk of my game collection (the arcade games listed come from compilations I've bought, though I do have an actual PCB of one title
). I don't think I'm going to be bored for a long long time. (And if you guessed that I like platform games a LOT, you win a cookie.
)
In addition to those, I'm also very much looking forward to PandoraPanic!, Superlumenal, Galactic Artifact (if indeed it is released for the Pandora
), and ports of things like SuperTux, Quake II, Solar Wolf (if do'able
), and so on.
I'm probably forgetting a whole bunch of stuff, but this post is plenty long enough as it is, now, so I'll end it here.
