I agree with all of the above, but add EHZ1 RA for a bit of a feel (or at least easy stats) for S2...
and probably leaning strongest towards S3DB if you can get good with the controls (the ONLY game that I CANNOT play on emulator... I'm better on console, about 90% of the time, but S3BD becomes unplayable)
If you want to try at all for the GG games, they really aren't that bad... especially thanks to Sprint, who posts his movies on his most excellent runs.
I'd personally say that you could try some TUSC stuff as well, but I'm sure that's not your style, since most people dislike it ^_^
