Yeah - football with guns.
The one with the biggest gun is the one to watch. Why does he always score the most goals?
Doing anything with camera views other than the default is not going to be easy in FPSC currently. That does not mean things cant be done - I am sure - just that to needs someone to put the effort in and try and see what can be achieved and maybe fail after a lot of hard work. But unless someone tries we will never know.
Personally, I am not in the game of trying to defeat FPSC in areas that is not designed to compete. Results at best are likely to be not professional enough.
The idea of carrying and throwing of course is now possible - an enemy for instance could poosibly throw a football and not a grenade and the player can now pick up and throw stuff around. A football game is rather more complex than that of course with many things really required to be of a much higher level of sophistication than that which FPSC will allow.
Advanced Pathfinding, AI and desicison making capabilities, Group or Team Communications and camera control are only some but perhaps the most important of those needed to make a professional looking game of this nature. All these things are really advanced requirements - very advanced - if you want even a reasonable result.
Script it yourself - well maybe - you want to give it a go. Not me. Personally I recon this is a non starter cuurrently. You might achieve something very simplistic - I guess that could be done.
Perhaps when these areas of FPSC become more advanced and the scripting becomes more flexible and user friendly, then more professional results will be possible in such game making scenarios.
When V1 is released you will be able to adjudge for yourself the new capabilites. Ceratinly they are extremely good and fairly advanced with the suport of good thinking and scripting effort but not quite to a professional football type game standard yet I would think.
Who knows - try it when you get it and see what can be achieved.
After that - If TGC are willing to continue advancing the program you may have more options along these lines somewhere down the road.
