At least the ending motivated me to register on bioware forums just so I can complain about it. I think the OP had a very fair analysis, and I think he is right that the statement comes from a place of fear. Also pain. The creators and investors of Mass Effect probably thought they had a ****in' ending, and this criticism is coming entirely out of left field for them. They probably don't want to change it because they had been working up to this point for five years, and now people are whining and what they want to say(but can't) is "tough balls. You write an epic 3 game trilogy and then I'll tell you that you suck, how's that?" They have a right to feel hurt and insulted, but as fans and consumers we have a right to demand.
We were told, and therefor we expect, that our decisions would drastically effect the final outcome of the game. They didn't, and I defy any bioware defender to argue otherwise(probably going to regret that, but there it is) The whole point of mass effect is that you craft the story. You make Shepard be who he is. Want to make him a terrifying badass who shoots first, asks questions later, and dooms a whole race to extinction because the other one is more useful to him? You can do that. Want to make a peace-brokering hero who finds the diplomatic solution to everything and unites a galaxy under his banner, losing a few allies in the process? You can do that to. The problem is that both of those Cmdr. Shepards suffer the same fate, as does the galaxy they molded. I want an ending that is epic, that requires sacrifice and tough moral choices, but reflects on the character that I have created. I'm not alone in this.
What Bioware and EA do not understand about gamers is that they speak with their wallets last. We will **** and moan but at the end of the day we will buy whatever DLC they throw at us in record numbers and thank them for the **** they are shoveling down our throats. I don't know why, but we will. I'm not going to bother trying to change this, but what makes me sad is that by the time all the bad decisions monetarily catches up to Bioware it will be too late. By the time fans stop buying their games there is nothing else to say. They left. That's it. So yes, angry forum posts don't equal less dollars in Bioware pockets, but they will in the long run. Next title that comes out, how enthusiastic will you be? Personally, I can say not much. I'll look at it skeptically, and if it looks like it will truly blow my socks off I will read some reviews on launch day, maybe pick it up a week or two later if I have the spare cash. I will not run around like a crazy person trying to scrounge up a N7 collectors edition from random Targets like I did ME3. I have been disappointed too much to let myself get that emotionally invested in a bioware game again. Unless you come out with satisfactory ending DLC, which should be free but i will probably buy anyway. If you do that, I'm back because it means you really do care. Until then, I watch bleakly as they release statement after meaningless statement that makes me angrier than their last meaningless statement. So when Bioware is wondering why there isn't more hype for their next franchise launch 3 years from now, they can look back at this and other mistakes and their responses to them.
