I think this game is fun. I havent seen any problems with the physics really, and It's fast sure, but the models are big and spaces wide so I guess you will have to adjust. Really, I found my shot to hit ratio with sniper rifle better than the Q3 rail so I guess thats good. I think when you all get the retail and there are lots of maps, with maps coming out soon afterwards by the buttload, you will be happy. That and a dozen different player models will spice things up.
One of the things I enjoyed most about Q2/Q3 was custom maps. In a year there will be hundreds of great maps and some new great mods, so give it time. It certainly appears they are off to a better start than Q3, which, IMO, underperformed. But oh well, time will only tell. Like I said guys, if y ou cant just enjoy it, then maybe you are a ilttle too much into video games, or at least this genre, and need to diversify.
