after you finish the single player campaign, can you continue to do battles and earn c-bills and build your team of mechs? i know there is a stadium mode, and is i think i read there is a random mission generator?

Instant Action is the only thing I remember for quick replay value, but if you want to still be able to fight in the coliseum in campaign mode, don't due the final planet.

if you dont do the final planet, can you keep doing other campaigns at other planets for as long as you want?

All of your contracts are short-term which means that, after you have finished all of the missions on one planet, you must go to another to stay in buisiness.

what i mean is, are there always missions for your crew to do? or are there a limited number of missions, and after you do all of them you can only fight at the arenas?

You can keep fighting on Solaris VII as long as you do not go to Tharkad, Carse or New Canton but other than that, there are only a limited amount of missions.

Quite true, though playing all of the campaigns through is worth it. if you want a cheap, vague rundown on these, search for the movies within the game and watch them...IF YOU DARE!!!MWAHAHAA!!!!no.

I miss the gameplay of MW1, where there were endless missions at different planets..
