I think that would be an extreme but solid solution, and I would buy it again
Like Grobut said, they should review the way UT3 is installed on the PC.. I think 2k4 was better in this point because it had just one folder with everything you need on it, and the whole 'my documents' setting is a bad idea for a game thats supposed to handle lots of custom content like Unreal... keeping the UT only folder like 2k4 (but adding some new folders in there like Custom Maps, Custom Materials, etc, just for the sake of organization) would be much better imo... this and the in-game UI of course, that should grant the player much more control over his game, more options to mess around...this can't be solved by patches right?
As far as content is concerned, UT3 is good, but could've been much better. In 2k4 days, almost no game was as big as it was (5GB stock install, something like that right?), but UT3 is not like this. I was expecting a 12GB+ game when I got it, and I don't think that this amount of space is a problem for anyone now, there are much bigger games now (Stranglehold, for instance)... and being more especific, UT3 lacked some Unreal "trademarks" that shouldn't been trashed (yeah, the whole skaarj/malcolm/xan/flak monkey/combo whore/ripper thing), and for a storyline-driven game, its characters and the whole thing was too blank (look at the characters description... most are just "this character is cool and kick ass"), not to mention the lack of "classic" themes like alien-ish(Necris theme is really really cool, but UT3 still lacked the space/alien-tech feel that we had in Hall of Giants and Hyperblast)... this CAN be solved by patches/packs, although, if it'd include almost everything that the community wanted and asked for, it could get bigger (in proportion) than the ECE for 2004... wouldn't make me give up on downloading it though...
So, for a entirely new game, thats what would make me buy it (and it was kinda what happened to the unreal series when 2k4 came out to make up for 2k3)... I'm having lots of fun with UT3, but would love to see my favourite PC game to get revamped and be a huge hit on the market. Again, I'm enjoying UT3 a lot, some great maps are out and more are coming, and this topic is not a "omg bring [random stuff] back plz!!1one!" =]
ps: finally decided to post here since I lost my account some time ago (dunno what happened though...)
