Mainly because of the Nostalgia and my age at the time, my favourite pseudo-console was the TI-99

Not only did it have games on cartridge, I was able to program a couple small games of my own (keeping the code under 64 MB)

I spent hours on Munch Man (Pac Man) and Alpiner.

I think it's because of that little keyboard that , even though I loved my NES, I've always preferred PC games to console games.

But, for a true console, just because of the Zelda/Link series. NES is where it's at.
