I can't remember where is was, but I saw somewhere that either in OFP 2 or a new version of OFP, MP games that have already started can be joined (mainly just DM games).
So if this is possible, how about one big mission that is based on the CTI missions, except that it either lasts a long time or never ends. Each team actually STARTS with a base, but there is no real commander.
New defences can be build with the repair trucks and stuff, but no new factories can be built. The team's bases are on either side of an island, Nogova for example, and they might have a few pit stops and stuff. Teams would have a meeting tent or something where they plan attacks, and various things like that. An ongoing war, basically. Loads of other things coule be added, for example hospitals in towns, people who take you into their home and let you rest and you can heal there. You get the idea. Any comments or ideas?
Also, let it be known that if anyone does this, some credit should be given to me
thanks!
