is it possible to add multiple ( 100, e.g. ) clothes/capes/pants into a game,on modern hardware, using cloth simulate techniques? wonder whether it make sence to spend time working on it... thanks in advance.

That realy depends on the level of detail of each piece of cloth, and how many objects they collide with and so on.

I don't think you'll have any problems with more than 100 pieces if you make the simulation as easy as possible for each piece. For instance you should only collide the cloth with primitives like sphere's, boxes and similar objects. You could also limit the collision detection, so that a cloth simulating a pair of pants only collide with the legs and nothing else. If the pants are tight then maybe you only need to simulate a small part of the pants (a small piece of cloth at each ankle).

World Of Warcraft has capes and tabards and whatever which all seem to be cloth simulations, and are all quite different shapes and sizes.

On the other hand, they also often intersect things they shouldn't, and they seem to have decided that if a piece of cloth gets too far away from its rest position to just reset it, so if you lie down your cloak will slowly slide down into the floor then leap back into place. All in all it looks ok.

capes in WOW seems not to be implemented by cloth simulation, but bone animation. you may find bone animations in their data file using "MyWarcraftStudio" or things like that...

one time-consuming part of cloth-simulation may be the collision part, including collision with body(for clothes) and self-collision. get rid of the latter one may increase the fps but i wonder whether it'll be too "fake"...
