I finally got around to trying Tremulous, a former Quake 3 mod gone standalone. Wow, I can not understand why this is so popular.
First off, a major strike in my opinion, there is no way to change options from the main menu, as far as I could tell. I had to connect to a game, in 640x480 resolution, to be able to change any options at all. I don't think I've ever encountered such a perplexing setup. I'll admit right off the bat, maybe I missed something, but on the main screen I saw three options: "Play", "Mods" and "Quit." No options to be found.
Secondly, I've got to assume that the people raving about this game are playing clan matches. The foundation for some great gameplay is there: buildable fortifications, widely differing character classes for each side, I could see this being a lot of fun. But on public servers all I encountered was a bunch of people calling each other "noobs".
I understand that in any online game there are going to be stupid people who call each other stupid names, but the volume of name calling was fucking unbearable. I quit the game and promptly uninstalled.
Hey, Tremulous is popular, it doesn't need my help. But that doesn't change the fact that I'm never going near the game again.
