Gamebase20 is now well over 2,000 entries in total, bolstered mostly by all the German magazine type-ins and discovering a fistful of missing Compute listings. There's still much more out there, I discovered two new commercial games just this week and am negotiating to obtain them from the owner. I reckon 2,500 is easily possible, probably 3,000 overall given enough time.
What about another release, I hear some of your cry. Well, given v0.2 came out at the end of 2009, then the plan is to release something by the end of this year... so v0.3 approaches shortly

Lie with passion and be forever damned...
