I like games. Before I had kids I used to play them a lot. Now, not so much. My favourites:
1. Rygar. Played this on a caravan park in Wales several times a year from the age of about 8 - 14 but never knew what it was because it was the Japanese version. Found it years later on MAME and still think it's awesome.
2. Bubble Bobble. Never played an arcade cab but have it on every system I've owned that it's been available on (I go back to the Amstrad CPC 464 and C64, so it's a fair few versions). Another one that doesn't age.
3. Super Mario World. The best 2d Mario. Which makes it one of the best games of all time I think.
4. Zombies (Ate My Neighbours). I've never seen anything with this type of fun, B-Movie atmosphere since. A pure joy to play.
Of course there's lots of others, LOZ Orcarina of Time, R-Type, Alex Kidd in Miracle World, Sonic 2, StreetFighter 2, Super Mario Kart, Tetris, Devil Crash, Micro Machines 2, Speedball 2, any Castlevania (Rondo of Blood is awesome, only played via emulation though. Would love a PC Engine)...
