Welcome to the Sony realm my friend. Congratulations on you very first Ps3! You got the slim one, right? 120gbs good enough for you in my opinion unless you are 10x's of a gamer then I am. I only have 80gb but rarely use any memory at all. The Ps3 has everything we all need all in one machine and one price. That is the best bang for the buck for a console system. Plus free online networking.

Best games I think are out there I know of would be..
*Metal Gear Solid 4
*Fallout 3
*Gran Turismo 5(coming out soon)
*Street Fighter IV
*Final Fantasy XIII(coming soon)
*Assassins Creed 1&2(never played it but it looks cool)
*Devil May Cry 4(never played but know its good)
*Bioshock 1&2(played a bit and its very interesting)
*Nba2k9
*Resident Evil 5
*GTA IV
*Call of Duty 4(never played but is very popular)
*Deadspace(probably the goriest and scariest game out there for now)
*Guitar Hero(never played but it is very well known)
