Just my feelings regarding this overrated game:
Wow, such an insightful and unique posting for a troll.
There are many former UT2k4 players playing UT3. Almost all the clan players I know played UT2k4. That said, UT2k4 was great for it's time, but that time is over. All the UT games were fantastic. UT3 had issues when it was first released and it took a while to fix, which hurt the UT3 player population. Much of the blame goes to bad video drivers from both ATI and NVidia, incomplete and poor quality beta testing, and then releasing an unfinished game (EPIC).
UT3 is still a great game and still has online activity. Just as with UT2k4, players must deal with the learning curve in order to gain skill and rank. Players must learn and master UT3 movement in order to survive online. I like the movement and weapons in UT3, all better than UT2k4 except for the lightning gun is missing.
One thing is for certain, the more you play UT3 the better you will get at it.
