just beat SR2 it was fun but for some reason I was not satisfied with the ending.... what the hell was that with killing the Saraphan Raziel! he wasn't even hard to beat! Also it dawned on me that now that I have beat SR1 and BO2 that the last comment of Kain made sense but in all reality anyone who hasn't played the other games especially BO2 would not get it at all.
other than all of that i did enjoy the puzzles.. although I liked the Puzzles in SR1 better, but still i had to leave the PS2 on once in awhile to figure somethings out.
