Had a couple of bites in this months issue (free subscription). ANyways. They had a list of top 5 unbeatable games (for them anyways)

1. Ultima IV (NES)
2. Blaster Master (NES)
3. Ikauga (GC)
4. Tom Clancy's Rainbow 6
5. Kid Icarus (NES)

Then a little further back in the mag there is a little blurb asking ricky wiliams about some stuff he owns etc , and he said has an emulator and loves playing mrs. pacman , pac-man, double dragon so I am guessing either mame, or some nes emulator.
