Speaking of which, I have just, this minute, finally bit the bullet.
Covered my Mass Effect 3: Disc One with toothpaste, rubbed it right in, and then washed it off by dunking it in soapy water - absolutely terrified throughout. Feels wrong, doing that to a disc. Absolutely terrified, petrified that I was just making my problem worse and worse. But... it works! I've installed it to the Xbox, now, so as long as it recognises that I've put some sort of Mass Effect into some sort of drive I will never have this problem once more.
So, I can finally play single player again! I cannot wait. I'd just started an "Insanity"-difficulty run to get my final outstanding achievement when it all went kerplodey. With the new weapons, too. Joy unbound! Mass Effect 3 hasn't besmirched my loyalty in the slightest. Love it to bits. More, if anything. Beautiful, beautiful game. Beautiful trilogy. It's going to be a triumph. Bring on the insanity.
Also, fear I probably know the answer, but... anyone else still playing multiplayer? Collectors!! Turians with jetpacks!! Playable bloody volus!!!
New character tomorrow. Can't wait to find out what.
