Ah, I figured there would be a topic on this subject here. The ventillo community, eBUM's have been talking about this for awhile also. So far we got around five pages worth of written work and ideas on this. Not sure what were gonna do about it though. The idea for it, is that it will be MMOFPS(naturally), but also have a mix of Eve like elements.
Start out as regular grunts, and work you way up the tree in ranks, earning your right to use mechs, and higher level mechs in such a way. Then engineers would be able to come in and salvage parts of destroyed mechs, or completely salvage mech bodys, and refit/repair and sell on the market, ect.

I wish there was a newer modern mmofps war based game out. Planetside was close but I wouldnt mind seeing something more relative todays technology but on a massive scale with air,land and see forces. That would rock.

What Deneme said, we've been talking about it in Vent, and really hope to one day pitch it to a company. We had a more... MechWarrior-ish idea of it though, not like the anamorphic mechs of Gundam and Evegenlion, though. But yeah, I hope we do get to get into production(somehow), not only to live the dream, but to have an awesome game sculpted in our vision... With free membership and a percentage of the sales, maybe?
