Hi,
the leaving of the PoP team makes me think of the situation of modding for ET.
Actually I watch the player numbers for several games very regularly:
http://www.csports.net/(pzwxzd555eoppm55lu0vnvzg)/TopGames.aspx
Strange situation:
The playerbase of W:ET is nearly unlimited (names in 31 days: 1,355,886).
But there aren’t enough modder.
The playerbase of HL2:Source is limited to the owners of the game.
Although there will be players that would buy a game for a mod I think the number won’t change that much.
Names in 31 days at the moment: 379,225
There are enough modders around.
Most played ET-mod (total conversion):
True Combat: Elite
Names in 31 days: 29,790
Most played Source mod:
Dystopia (actually it’s Garry’s mod but I think this is “only” a fun mod)
Names in 31 days: 11,930
Very strange.
ET: unlimited playerbase - nearly no modding activity - nearly no mod players
Source: very limited playerbase - very high modding activity - nearly no mod players

Oh how I would love a freaking shotgun model though.
