i agree with you that they are taking a direction which can go wrong, but also can go right. personally i think that mass effect 2 is a better game then ME1. you can disagree with it, but i think that ME2 was better in every way. it played better, there were more really interresting characters. the action wsa great. they had soem tweaks with talking to people. it was just great.
adn with DA2 i can see why people think its lesser the DAO. the combat system was way better though, more fun to play, and still tactic on the higher levels, but there were few orginal levels there were some problems with spawing enemies, what took you out of the experinience. and indeed, soem characters were lame in DA2. there were some who were golden, but most were pretty generic. the main problem i had with the game, was the invertory system. why cant i give gear to my party? and why would i need stars to see what is better. and the only decision you had when you had chosen your class, was what kind of weapon you wanted. which gear you needed was always the same.
and for ME3? i find it weird they want to take out the stats from the game, cause to my idea there were never so many stats to begin with.... so yeah, i do fear that the game only will be action-talking. but we can'[t be sure till we see it.
oh yeah, to be said, i never played baldur's gate, but if you like it so much, why don't you play that?
