rare made games for the spectrum before they were called rare. *Edit, i belive they were called "ultimate Play the game" back then.
i dont think ive seen that thing before, it looks like that one toy (powerman i think it was called?) that had a saturday morning cartoon that had sections where you shoot your tv and the toy counts your score.
wii, wiiu, and 3ds have a decent library of successful hits in their virtual console, psvita, ps3, and psp have a good chunk of ps1 games (ps3 has some ps2 games). Sure youll never see games from some less popular systems like the zx spectrum mentioned above, but youll have a good footing on true gaming classics (and lets be honest, the NES', SNES', and PS1's libraries make up ~75% of the best 'retro' games.
this is filled with kids, few remembre spectrum :)
the "rainbow slash " bane talked about would be a screen that would eb showned while the game was loading, which means half na hour (at least i perceived it as being that long but you know, i was a kid back then).... sometimes it would load for half na hour and give na error at the end
there are few atari games worth getting if youre just starting out with classic games. most are terrible, and a few are only worth a look only as a peroid piece. none are the master classes of gameplay like mega man 3, mario, zelda, ect. the NES is a good place to start because it actually has good games that are worth playing for fun.
