as with many people on here, i have also got Tomb Raider on the 3, im on the final boss, and i shan't be purchasing for the 4, no point for a few graphical updates.
im not even sure i would purchase The Last Of Us on the 4 (if the GOTY edition materialises, as is the rumour), but i can't wait for TLOU 2, if it gets made!
AC4 i have just started playing, never played any of the others before, so its all new and so far its all good. graphics are amazing and i have spent hours on it and only just made it to Nassau!
Resogun is quality, love all the particle physics!
