Isomorphism - you really feel that the core gameplay is much better? I mean, I can understand saying the graphics are better, or the dialogue system is slightly better, but the core gameplay I disagree with. In my opinion, the inventory system alone wrecked the core gameplay compared to previous Bioware games (even pre-KOTOR). Regarding the Mako, I never hit the point where I was happy with the controls, even after countless side missions and random planet exploration.
Spuddyt - sorry to hear that, I wasn't hit with them that frequently but at times it would happen once every couple hours and it always would happen when I hadn't saved my game for quite some time. Needless to say, playing through something once is ok but being forced to go through it again because of an error, well, it sucks. It's what I'd expect during an alpha or beta build play through, not retail.
rechicero - Thanks for your feedback. When I discussed the review with Rob (Tom's Editor in Chief) prior to writing it, he specifically said that we should be spoiler free. It is nearly impossible to reveal anything about Mass Effect without spoiling it. You can't discuss the Mass Relays, you can't discuss details about extinct alien races, you can't discuss details about your arch nemesis and why he's doing what he's doing, etc. If you hadn't read the prequel book, you're literally tossed into the game knowing nothing, and I wanted to make sure that even after reading my review, people still really knew nothing of the story aside from it being something they should experience at least once.
Also, consider the fact that I ran out of room to write. When I submitted my review, I believe it was sent in at around 2500 words, way beyond the 2200 cap that we aim for. When it was edited down, it was still over at 2250. While there was much more I could have gone into, I literally had no room to do so, especially after venting the issues that I saw so many other reviewers brush off. There was no way that I was going to skip what I considered major issues over something like going into the characters themselves. To be honest, I really didn't like the characters that were on my side all that much, and I really only "used" them for their abilities more than anything else. I much more enjoyed the characters supporting Saren, or even the council. I'm sure Bioware really did their best to make all of their characters likeable, but the party NPCs just weren't as life-like to me as the characters involved with the story. The one exclusion to that was a confrontation near the end of the game regarding a party member and his race being almost extinct (if you've played through, you know what I'm talking about).
Also, keep in mind that I suffered from Disc Read Errors, and had no help from anyone at Bioware even after posts, PMs, and emails inquiring about the DREs. The only people who have tried to help me at all is Microsoft tech support. I believe that the DREs are something that Bioware should take more responsibility for, and at the very least help people get the $99 or higher fee waived if their 360s need to be sent in. The saddest thing of all are the people now complaining about DREs after paying for a repair, only to continue to get them. There has to be a better solution, and Bioware certainly has the resources to help people.
In terms of sci-fi, fiction is really fiction, so I wasn't going to knock them on the Mass Relay concepts. The general public would buy that, but the whole weapon and upgrade progression, no way. Humans respond to marketing and product differentiation, that's not going to change in the future.
A 70% is still a good score, and I still recommended at the very least a rental. We're working on following new review guidelines which are a bit more strict. Rob should be posting up details of this sometime in the future, but we've already gone over it internally. Anyways, I just expected more out of Bioware. Perhaps if it had been a brand new developer without any solid experience, and the DREs didn't exist, I would have been slightly more lenient, but even then, not much.
Edit (or stealth update) : Regarding different endings, side-quest options, etc., I did a heck of a lot of research on the official forums, Gamespot forums, GameFaqs, etc. prior to writing my review. I realize that there are different endings, and different ways to approach situations, but they're not all that different at all. While we can't obviously debate this in detail, I read all about the alternatives to make sure that I was considering the quality of the story as much as possible. The story is great, which I said in the review.
