1) There are 6 different classes.
2) Yes but it's extremely cool to have a shotgun to shoot centaurs, even if it's out of place. <!-- s;) --><img src="{SMILIES_PATH}/icon_wink.gif" alt=";)" title="Wink" /><!-- s;) --> Don't worry, the Korax' Heritage RPG will have no such inconsistencies. But KA is primarily about gameplay, for example in my personal opinion some of the UT map conversions (the industrial ones) look more out of place than the shotgun or the rocket launcher, but they enhance the experience. That said, you can always set up a game using fantasy-only maps and fantasy-only characters.
3) The idea is cool, it'll be considered later on. Currently, main focus is on single player DeathMatch with bots to work as good as possible, once it's good enough KA 1.0 will be officially released. No ETA though.
4) Those were links to the 0.1 and 0.2 public demos and we're at about 0.9 right now, so they don't make much sense. The latest movie trailer should give you a lot more insight into the game than those old public demos, see <!-- m --><a class="postlink" href="http://www.korax-heritage.com/forums/viewtopic.php?t=1552">http://www.korax-heritage.com/forums/vi ... php?t=1552</a><!-- m -->
