Great idea. I agree about EDF. Hardest achievements I've ever personally come across.
I haven't noticed any drought of good games, although it's probably because I have been making up for lost time with Oblivion, and I am in love with Shadowrun. Incidentally, Shadowrun gets 7 buckets from me. They'd be somewhat easy to get if you play to get them, such as getting into a party with friends for that purpose. But I'm just playing for fun so it's taking forever. I'm at least 40 hours in and I probably have around 400 points.
