RidiculousMammal, you do realize not every computer is capable of properly running Mass Effect, right?
As to the topic, I am a person who plays Mass Effect on Xbox 360, PS3, and PC. There are reasons [aside from me being a collector of the series who just loves playing the games that much] why I use all of these options.
Why PC?
1. Mods. I love mods like one that doesn't force the first cutscene of Arrival on you until you want to see it in ME2, graphical ones [and mods that let me avoid texmod], and other content ones like restoring Anderson's final conversation with you to what it was going to be.
2. even without mods, it looks even better on PC
3. Gibbed Save Editor and coalescend editor are a LOT more simple on PC than the consoles [in terms of easiest to hardest: PC >>> Xbox 360 >>>>>> PS3].
4. easy access to collector's edition content. I didn't get a gaming PC until 3 months ago, so obviously getting a physical collector's edition is all but impossible with unused DLC. with STEAM [which I bought ME2 Digital Deluxe from] and Origin [which I bought the trilogy set on {for the Pinnacle Station DLC in ME1} and the ME3 Digital Deluxe $10 upgrade on]. What really made me happy was the fact that me buying the digital deluxe edition of ME2 not only gave me the collector weapon and armor on the PC version, but it ALSO gave me the Xbox 360 version of the DLC too, which I never could get since my ME2 collector's edition on the 360 was used.
Why the consoles?
1. I am far better at using the controller of a console with these games than keyboard and mouse. Sucks that Bioware seems to be against adding controller support for Mass Effect games on PC.
2. achievement/trophy collecting. These are 3 of the few games I can get the max score/platinum trophies in. I enjoyed doing it on the 360 so much that I wanted to redo it all again, so I got the PS3 version and did it again.
3. the PS3's free online. Sure, online on the PC is also free, but on PS3, I also have the benefit of using a controller instead of keyboard and mouse.
