Actually I think there is more overlap between the "space sim" and RPG crowd than you give credit for. While you blasted it, look at say EVE Online. Also while it underperformed I saw a lot of potential in the old game "Earth and Beyond" which struck me as something that would have worked well as an addition to another game.
Not to mention the amount of time *I* put into games like "Trade Wars", "Yankee Trader", "Terra Firma", and "Galactic Warzone" on old BBS systems before I ever got onto The Internet.
At any rate, I do agree that they could do more with Mass Effect, and I also think that the "buggy" sections were a good idea, but hideously implemented. I think they really could have made the Mako fun if they had decided to work at it rather than scrapping the whole thing.
Good luck with the space game. I don't know how many people played your "Fantabulus Space" game but I thought it was fun, so I look forward to your next effort.
Incidently your freeware game design efforts are one of the reasons why I have so much respect for you, and your opinion, even when I disagree with you.
