Heyyo,
To me I loved Q3A better than UT. UT feels very slow, and I played it only for that Marathon|Rampancy mod. For back in the day I say Q3A>UT.
But now Q4 vs UT2k4? UT2k4 = 32player, huge levels, great netcode, and improved bots. Q4 = still 16 player, not very big levels infact some feel smaller than Q3A, netcode's good, but no bots. It's a no-brainer that UT2k4>Q4.. sure it's nice to see they tried to keep it as similar to Q3A as possible, but they should've added onto the series I say.. which saddens me cause I was hoping Q4 would be a very nice improvement, but it's just all graphics.. I'd rather play Q3A cause of the hella smart FPS bots, one of the best.. I'll never consider Q4 to be an improvement if it goes from soo good bots to none. To me Quake Enemy Territory will be much better than Q4, or at least it better be tons better or I ain't buying.
