i dunno what game to get mw3 or metal gear solid hd collection. Both good games but, mgs doesnt have much replay value to it. I kinda promised myself i would never buy another cod game by infinityward but now i find myself in a delema. Both games are fairly cheap. MGSHDC--$40-45 on ebay brand new MW3 around $509(new) will mw3 be just another cod that i will see sitting in my game collection after a few months and regret ever buying it?
Honestly, try something other than those two. If you doubt the replay value MGS (which I do as well), and I definitely agree on not getting another CoD, it's the same god damned thing. I'd recommend Battlefield 3, it is absolutely mind blowing.
As above, BF3 whether you get on PC or console is a very good game. MW3 is a re-run of MW2, they have copied so much over and I got bored within 2 hours. I play COD4 more than anything now.
