What UT needs back is its humor. Killing yourself in UT2004 is always hilarious, Killing yourself in UT1 and the Homer like "DOOOOOH" makes me cry laughter all the time, but for UT3 when you die somehow I am reminded of beetlesborgs, "You'll pay for that!" "I'll have my revenge!" " AYAYAYAYAY Zordon I have died," "MUAH!"
What makes Unreal is what is Unreal.
What is life like for most people? Not funny, not fast, so many problems make you unhappy? Neonite's reign of terror?
Unreal is funny when horrible, the problems make you stronger and more you find the happier you are to do them. Everyone whose played Unreal 1 has seen the first skaarjwarrior, who runs like a coward when you open some door. When I first saw that I thought "OH MY GROIN!" but afterward I found it hilarious, then soon after that I just felt sorry for the poor victim, He has to shredded to pieces about 20 times before I maintain not killing myself for some reason.
Unreal is what made UT franchise start, and its because of UT1, UT2004 thrived afterward. Yes alot of UT1 players do not like ut2004, but because of how many fans of UT there are, they influenced others to try UT but the latest one.
Here is UT3, UT3 comes out 3 years after 2004, in between these two titles, what has happened? Nothing, there was nothing like unreal 2003, nothing like Unreal 2. When UT3 is advertised, was 2004 a catalyst in adverting? Did they mention UT1 alot in their advertising? What they did wrong was relate it with Gears of war, "From the makers of Gears of War" this is what turns off most of the players because now they are thinking they are buying a single player game, 8 years from UT1 the gamers who couldnt play 2004 and UT1 and now able to play these type of games, and UT3 was treated like they already know the franchise.
Unreal 1 came out in cradle of the FPS future, but now we are in that future but the future is not mention its past, its not telling the stories of its youth and thats the reason why titles from the old school cannot thrive.
When Bioshock was first advertised, it told something new, it started a new story. World of warcraft will not fail, because its not always the same over and over.
The biggest failure of the franchise is the weapons. The weapons are the same ones for over 9 years now, and all those years in the Unreal Story they have not changed, they have been balanced and such (Something patch would do rather than a whole new game) but its still the type of gameplay, same type of moments, non surprising situations, the only thing new is sniperrifle is a shame to its brothers lightning gun and UT1 sniper.
UT can be revived once its story, weapons, and characters get a transplant.
