Quote - This will cause me to buy the PC versions of Mass Effect 1,2, and 3-putting $180.00 into their coffers

That's a trifle excessive. ME3 goes on sale for $5 frequently at Origin, and ME 1 and 2 are bundled for about $30 off sale at Steam; wait for the summer sale and they're practically guaranteed to go on sale. No need to spend more than about $20 for all three. ;) That's not counting DLC, of course, which is still exorbitant. :(

(That said, there aren't very many mods for the franchise. It's not a very mod friendly game.)
