Some good points raised in this thread.
First off, I'm not opposed to different realism modes. I actually think that's a really good direction to go in the long run. The issue is that our focus right now has to be on getting /one/ mode solid, and in the interests of accomplishing that, I feel we have to focus on avoiding elements that will feel clunky or obtrusive to most people trying to get into the genre.
Having a solid barrel/turret as far as environment collision is concerned will be a major hurdle to overcome for anyone approaching this type of game for the first time and I'd rather not have it be a turnoff for potential newcomers to the genre. In the long run, there's a lot of merit to having two+ levels of realism that players can queue for, but we can't start there.
Thanks for the video link, Boogie Van! That was great to watch. I'd never seen it before. Forwarding it on to the team now.
The consideration about the barrel collision being a valid concern for some types of vehicles and not for others as it pertains to areas they can go on the map is a good point. It gives me something to think about for the future.
