I'm wholly confused here. I payed 125$ for a copy of Steelbeasts a while back. That's, arguably, quite a lot for a PC game. Now, I know it's a top class simulator used by DOD's around the world, including my own. I know it's a pretty damned good simulator (I've been manning the CV9040 in real life and could vouch for Steelbeast's accuracy). And I also know I really like Steelbeasts and was willing to pay for it. But, now it seems like an upgrade would cost me a lot more money. Hey guys: I bought the game/simulation once!! I love it, and I appreciate what you are doing, but I think it's a bit over the top to be required to pay for an upgrade, yes!?! I will probably pay (just because I like your product), but I don't know of any other PC application that requires a hefty new payment every now and then. I rest my case. Just wanted to let you know.
