Taken from JGF’s (http://javagamesfactory.com) download stats, looking at which index pages got how many unique visitors.
Note that there is lots of double-counting here; all you can say is that, in oct 2004, there were twice as many unique visitors to shooter as to platform. Still, it gives a general idea of relative popularity.
Oct 2004:
28% - shooter
17% - rpg
16% - strategy
15% - classic
14% - platform
10% - twitch
Nov 2004:

24% - shooter
18% - rpg
16% - strategy

Jan 2005:
25% - shooter

16% - platform
15% - classic
12% - twitch
Not that I’m advocating this as a way to choose what game to do next, especially seeing as the new JGF won’t be using these enforced categories so much, but I thought it might be interesting / helpful.
