I'm really excited to try this. I'm not against a Quake single player game, but also not overly interested in it. I love the aesthetic, but even though I'm a huge fan, there wasn't really anything all that special about that game. Parts of it were even quite bad. The multiplayer is what made it the thing that it is, and it's great engine and fantastic style. But I'd definitely rather see a new single player campaign in that style rather than in that of Quake 2. All that Strogg stuff is really done for me.
But yeah, excited to try this. Downloaded it the other day and still haven't gotten around to setting up a source port.
