I really like the idea of having a demo right on the homepage so people can see the general idea of what Nexuiz is about. I just feel that the demo video should show off Nexuiz better than it currently does.
Real life example: I told a friend at work about Nexuiz and how it is the primary FPS that I am playing, he said he would check it out. He went home opened Nexuiz.com and the first thing he did was watch the demo on the homepage. The next day I asked him if he played it and he said "nah I watched the video, didn't look like anything special to me". He did comment on how well the main page was designed though. The following weekend during the intermission of hockey night in Canada, I opened Nexuiz and started playing. He came over and said "That looks frickin awesome". As he watched me bunny-hop, speed cap the flag, laser off walls to gain speed...etc... he asked me if he could try it out. As the intermission ended he no longer had interest in the Hockey game. He says "I wish the demo on the Nexuiz site showed me what the game was really about"
First impressions are important. Just a suggestion to have a more appealing video on the homepage to show off the beauty and finesse of Nexuiz rather than just the purty graphics it produces. Sorry if this post shouldn't be in the Development section.
