The Uncharted series won me over about 2 years back and now my PS3 collection is probably just as big as my 360. Exclusive wise I just feel like Sony has brought a lot more to the table in the last 3 years. My 360 gets fired up now and then, but because Sony produces so many more exclusives I find I buy more multi-plats for PS3 as well since I just feel used to the system. Hopping from PS3 to 360 and back is kind of jarring.
So nah, PS3 has a ton to offer.
Its a little strange but what you just said is, the same exact experience I've had with my PS3. Baller !!!!!
