i have herd similar comments about ac4. i dont think its going to be a vast imprvment over ac2(free game) but the seamless transition from jackdaw to island to ocean will help.. the navel battle,roaming will help, the graphics will help. but as a package i think the storyline with those things mentioned will make it the best cod to date.
a pirate theamed game based around semi real work has yet to be touched.. o it should feel semi fresh minus the controls.
