Mmm... "no more" prequels certainly implies that there have been prequels in the past, which would be why you would not want more in the future. We have not made a prequel to a game (I will admit you can argue that KotOR was a prequel to the MMO, but that was not the intention at the time of making it) for any of our games. Are there prequl games in particular that you dislike that, maybe, you are confusing with our games?
Fans in the past have said they would actually WANT a game that takes place prior to the story of Mass Effect , possibly centered around teh First Contact War between humand and turians. Would that NOT be something you would want? Or do you mean, you do not want a prequel game if it featured Commander Shepard specifically (like the recent film reboot of Star Trek for example).
Details?
Oh, and we have not confirmed ANY post Mass Effect 3 games, whether they are prequels or not. This is all just speculation at this point.

Fair enough, let's speculate.
Speaking for myself, honestly, I have absolutely No desire to play any prequels. That world is over as far as I'm concerned.
What I would love to see, if there is any future Mass Effect, is a post-apocalyptic ME world(s)/galaxy...eh, universe? You know what I mean.
I wanna go forward. I wanna to leave what's dead, dead.
Post apocalyptic hoojamaboobery, please. Completely new main character and squad/companions. Perhaps even a main character that isn't quite so straight laced...marine and all that.
A past with a bit more skulduggery in it. Although, what the character makes of that skulduggery past would be up to the player.
I mean, I would think one would need more than a bit of a skulduggery streak in order to even survive in such a post apocalyptic setting.
I just want to go forward. If you guys make nay more, that's what I'd personally like to see. So, no--no prequels for me.
