I won't deny that having GTAIV on the system influenced my choice to purchase a 360 but I also knew that it was probably the most cost effective way to keep up with the new generation of games because I simply do not have the money to upgrade my pc, not at least until I stop being a student.
Ive yet to experience any technical problems with my 360 too, guess I was lucky
Also I also read an article that PS3 is already getting called the PS3DO by game industry peopel, if you get that you know your consoles And it seems PS3 has yet to make a massive impact as yet, which is unfortunate because the first 2 systems were very good, guess they made the wrong choices on this release. Im tempted to get a Wii as well should my financial situation improve, just for Super Mario Galaxy mainly, plus so I have a bit more of a party system for when friends come down
