Here is the problem though its not transparent I couldn't find how much credits a particular items cost, it appears from the boards it may be $15 a mech... WOW...

This is what almost all non-WoW and non-Guild Wars MMOs are doing. I played Star Trek Online for a few months earlier this year and things cost a LOT. New ships were $15-25, special uniforms could be $10, etc.

Even more devious, some ships you can only get as random drops from chests, and to open chests you have to pay real money for keys. So people may not really be able to keep track of how much they're spending trying to get some fancy ship when they're going for it a dollar at a time.

I guess the model is to hook people, and the real fans will pay $15+ for one ship/mech/item. Others will only pay small amounts, but may impulse buy a few bucks here and there til it adds up to quite a lot.

I play ST:O for about 150 hours and I think I spent about $10 upgrading the size of my inventory and bank. But I'm fairly disciplined about things like that...
