Yes I plan to add the option to turn on side rollback. I'm not sure what you mean by more control. By multimode do you mean multimod? There are modders out there who make those, if you search you can find it.
Wow this is a really ambitious project! I am wondering if you have plans to let people import their own daz characters and if so which genesis? Also import 3d assets for the sets/environments? Pretty impressive so far, wish you the best of luck with this.
If you are a Trek fan you should absolutely give this game a shot! Its very funny and nostalgic. The developer also did an excellent job of using assets that look like they're straight out of TNG.
