There are some great Vic-20 games. Omega Race comes to mind, as I was just playing it yesterday.

It is a fun little (and I mean little, 5k RAM, 3.5K usable..

) system...
The C64 is an 8-bit games monster. (Not going to get into a "whose better" argument)..
But, make sure you get a working disk drive with it..
FUN system....
The Amiga 2000 is interesting.. It will play all the Amiga 500 games, so it has some great games....
It's a big box..

I prefer the smaller Amigas myself. If you can get it for free/next to... do it. It's great.
If you're paying you might want to save for an Amiga 1200..
Note, I believe the Amiga 2000 composite video output is monochrome (like the A500), so you will need/want an Amiga RGB monitor or an adapter.
You can get the A520 (junk, bad quality, but works) or better, something like Amigamaniac's Amiga-composite/s-video a fairly inexpensively.
Or you can go crazy and buy a Amiga-VGA adapter...
Good luck..
