Wanted to throw my name into the "Thank you for making this mod!" hat as well. Been playing Arma II with some buddies for a while and we've been looking for something to make us jump to Arma III and stop playing Escape from Chernarus on A2 and we think this may be just the ticket.
Missions needs a little bit of work so there's some sort of 'goal', but otherwise it's pretty good and we've been enjoying it. Couple of comments/suggestions.
1) Really like some of your goals of possibly having capture-able bases and side missions that give the players a goal other than 'wander around and don't get shot'. Unless someone is crazy, in reality they wouldn't just wander the island trying to survive unless they were either trying to escape the island, or had a mission they needed to accomplish. Perhaps something as simple as there's a main point everyone is trying to capture and hold on the island. Team that captures/holds it for x minutes wins? Or multiple points can be captured, while points are captured you generate points and the first team to x points wins? Whatever you do for some sort of 'winning' allow that option to be turned off as well, so people can just wander and survive if that's all they want to do.
2) Would be cool if you could set it on how aggressively the AI hunts people. Right now we have no idea whether we're being attacked b/c we're being hunted or if we just got caught in a crossfire between Opfor/Blufor.
3) Option to limit the amount of heli's/airpower would be nice. Now it's all or nothing. Don't mind a few enemy helis, but they seem to be all over the place.
4) Seems great that you respawn with weapons you died with. I'm not 100% sure, but I think you respawn with full magazines for any weapons that you have. Don't know if this is a bug, or by design, just seemed odd.
5) AI seems a bit loopy at times. Might just be part of the A3 code, but I've run up to a truck with bad guys. They stare out me out the window. Then after 20 seconds, they jump out, and go prone on the ground in front of me, looking around until I feel sorry enough to shoot them with my M9 from three feet away.
If you haven't played the Arma 2 mod "Escape from Chernarus" it's well worth a look, just if you want some inspiration or some ideas. :)
Thanks again and looking forward to playing this more!
