i thought it was alright - for me it played more like ut99 than 2k3/2k4
i dunno about broken stuff - i just remember ppl complaining that the menu looked simplistic and didn't have certain graphics options, but i believe you if you say it was slated for other issues.
Anyway, the reason i personally didn't really get into it was because after no more than 20 mins of play the fun would wear off as i realised i was just going through the motions and didn't get satisfaction from that kind of shooter anymore.
The problem was never really the gameplay, i think most people will agree that this part of the game was just fine, the real problem was that it was half-finished, kicked out the door with only the bare essentials needed to release it, stripped of the polish and all the groovy extras that we knew and loved from the older games, and that it was a flawed premise, UT was allways about wacky fun, but here they where trying to convince us that we should take it seriously, that we where figting a war with glowstick guns that do no real damage in drab and boring surroundings.. they obviously wanted to rope in the GoW players with this one, but did nothing of the sort, and just cheesed off the UT fans instead.
But to me, the biggest flaw with this game was that they put so many limits on it, allmost all the options to customize the game, both in looks and its gameplay, where gone, the old UT's you could tinker with to no end, you could set up matches in so many different ways (and so many more with some handy mutators), and they had a lot of variety, all kinds of crazy maps and themes and player models, allmost anyone could find something they liked out of the bunch and set up a game accordingly.. not so with UT3, it was a "take it or leave it" deal, with allmost no options to play around with, barely anything that could be customized, and all the maps and models conformed to a central theme (that was both dull and a bad fit for this kind of game), and thease limits even extended to it's mod support, with poor support for new models, voices and no way to customize mutators from the menu, it was a lot harder for mods to change the game without having to make an entire Total-Conversion mod to do so.
The game just wasen't flexible like the old ones, so if it's narrow theme wasen't your cup of tea, you where up the creek.
The game may have been bad itself - phaps i didn't give it enough time to find out - but i do believe that changing tastes of fps players must be a factor - are there still ppl crying out for fantasy deathmatch?
It was obviously never going to have the popularity of games like "CoD: Modern Warfare" which was released at that time aswell, no, clearly not, this genre has become much more niche today than it was in the late 90's, but theres nothing wrong with niche, TWI makes niche games and that's why we love them, and likewise, there still exists a large group of people who want a good Sci-Fi twitch shooter, people who today are playing Warsow and Quake-live, and there where plenty of people who where very much looking forward to UT3.
But then the game came out, and half the fanbase for the title said "what the hell is this rubbish!? how could they have messed it up this badly?", and the other half said "i'm sure they will fix it.. lets just play it", but it wasen't fixed, the players who where not impressed didn't play, and the rest stoped playing too because there where never enough players to make it worthwhile, leaving behind only a tiny hard core of dedicated players, barely enough to keep 2 Warfare servers alive.
Niche games are fine, but you'd best make a game your niche market wants to play, or it's just not going to happen.. and that's UT3 for you, a niche game that failed to appeal to it's niche, not so much because it didn't play ok, but because it did not deliver what was promised, it was buggy, cumbersome, seemed half-hearted and half-done, it was too big a departure from the established theme in a vain attempt to draw in another fanbase who didn't care, lacked variety and polish, it didn't get the post-release support it so desperately needed, and even it's mod support was not good enough making it too hard for the fanbase to correct the problems (the toolkit itself is fine, but trying to incorporate your mod into the narrow structure of the game is a huge ordeal).
