For anyone on the fence about waiting for ME2 GOTY with all the DLC or not, it's $20 now, plus $5 and $5 for two of the main DLC additions. $7 gets you the other one, and that'll be less than $40.[/QUOTE]
Well, I already have ME2. Normally, even in that case, I wait for the GotY and
then wait for that to be dirt cheap

. The flip side of that, though, is that my points are already dirt cheap (and many were free) so spending cash even on a discounted GotY is not necessarily a better option.
However, I have already played through ME2 (on Insanity). At the time of release I maxed out all the achievements (1015/1015) but I did all that before the first DLC even came out (except for the free stuff right at the beginning of course). I guess there are more now, plus I do want to play my "correct" (paragon) ME1 playthrough. I screwed up and picked the wrong one when I did ME2 and then when I did Insanity I wanted to use my more advanced char so I had to continue with that.
I may just play it again with my better character on Easy so it is relaxing and play the DLC along with it.
So, that would be another 800 points spent (I'll wait on the newest one till it is on sale). Are there any achievements with the older DLC packs (the ones on sale)? If not, I just won't bother with them. I spent 800 on Toy Soldiers. And I guess this Costume Quest thing will be 1200, right? So I can get my 2400 with just one of the ME2 packs. If both have acheivements I'll just get both and "overspend" on the promo - no big deal.
