Saw you had just one post so I toned down.
Mass effect was nice, if not full of loading screens and such. But surely, you could at least give a group of games as an example, perhaps even show a trend?
Heres some expectations that you can be pretty assured of.
1. Multi-plat games will be essentially identical or for now better on the Xbox 360 due to the larger installed base.
2. The Xbox Gpu is more advanced than the PS3 GPU though both can be called very obsolete by now in PC terms. The PS3 CPU is more powerful so this is a wash slightly favouring the PS3. I don't think it's enough to call one as better than the other. Afterall true graphics philes need not look much further than a g80+ or 8800gt+ to get their fix.
3. Most games are going to be Multi-platform, if you like the exclusive frachises on one better than the other then thats obviously going to sway you.
If you're deciding....
Between Xbox360 and PS3. Go down from top to bottom, higher in the list means its more important in making a comparison. (From what I hope is an objective point of view.)
1.Value (How much you want to pay for games and INCLUDE back catalog of games that you want to buy at the start. Factor in whether or not you want WiFi and how important your online experience is. If no online and Wii is not desirable. Consider just getting an Arcade. It is PERFECT for just playing games and the lower price means you can spend more on games rather than paying for capabilities you don't need. I started with an arcade but I upgraded it. Furthermore is an Xbox360 arcade and a Wii MORE value to you than a Pro or PS3? Factor here also the cost of Older current gen games that are considered excellent and the value of the games bundled in applicable.
Consider the total initial cost of games and consider whether you value a better online experience. Factor in here for Online experience, what systems your friends have. If you play online a lot you're best to match them and get what they have.
2. Games selection. If you get a system that you can buy and enjoy games on the most. Factor in here controllers, you want to most comfortable and easy to use controller for yourself. Do you like RPG's? FPS's? Are you a refugee from PC gaming but still want as many PC frachises? (Xbox 360 rules here!) What system will you enjoy the most? Furthermore, which exclusive frachises do you like?
Here I think you should factor Known quantities higher than unknowns. Ignore hype, only upcoming games with proven track records should sway your decisions. Unless it REALLY sounds like you're going to love a certain game. GOW 2, GT5, MGS4, RFOM 2, Mass Effect 2, Uncharted 2. Proven high quality games with studios that have a track record.
3. BluRay (Only important if you are considering actually buying Blu Ray titles in the next year, Also factor in what type of sound system. If you have a decent setup or are an Audiophile, the PS3 is NOT a consideration here. Dedicated hardware is required. I have a PS3 and I DONT care about it's Blu Ray. I will get a dedicated box next year though. Lastly DVD is fine, really it is. I have a 53" 1080P screen and I view from 6' away. This is subjective
4. Expectations of reliability? One in 15 to One in 10 Xboxes will break down vs about 1 in 30-40 PS3's. Not hugely significant in my humble opinion. Mitigated if you have a Wii though. ^^
5. I hope it helps you! I tried to be objective but I have a little bias towards the 360. You can factor that in as well.
Tease.
