I have some ideas... *cue drum roll please*
1.)A Weapon Maker or importer, almost like Codemaster's, except it could take .3ds files and convert them to .x files...
2.)In one of your earlier videos, you walked up to a door, and it crumbled down and dust came out. Maybe in the level editor you could have a scripted sequence library, a start point for where you have to be (or step on) and where event takes place [i.e. a wall explodes 50 feet away, or the ground gives away underneath you, or an "ally" is running across a bridge but gets shot and falls off or something related...]
If they had these, the engine could very well be better than FPSC...
3. BADGUYS! Something to fight instead of having to resort to shooting the ground. Maybe an entity/enemy importer would be cool, with walk,run,shoot,jump,die,crouch,and maybe a patrol sequence...
PS:
Can you release it for free? I'm so tight on money it's not even funny. I just purchased 5 things - Model Pack 3, 6, 12, Abandoned City, and the Horror Accessory.
Any updates? I have the most recent post by 3 months!
