Prototype, a little too late?

With the release of Prototype this tuesday I have been asking myself for the past 2 days, should I buy this game or not. The main reason behind thinking about my purchase isnt whether or not it will be worth my hard earned money, but rather, do I have the time to sit down and play this game considering that, in the past 2 weeks, I have also purchased 2 other open world games. As you might have read before, I did buy and finish inFAMOUS the day of its release, and that isnt saying that I'm not still playing it, I have started a second game and am currently playing through as an evil character. Now the other open world game which I have not finished, and the game most of my gaming time is going in to is Red Faction Guerilla. Now back to my original point, do I really have time for yet another open world game at this time? I dont really know, I am usually quite strict with myself to get games on release day, a bit of an obsessive compulsive thing with me, but still, I dont know if I will be picking this up day one. Another though be it less important factor into my decision of a purchase is that, I have yet to see any reviews go up for Prototype, from the gameplay trailers and what not the game looks impressive, but I usually like to have some idea of what I'm getting myself into when buying a game full price the day it is released. This has saved me some money in the past (*cough* Star Wars the Force Unleashed). I supposed I will make my decision after leaving class on tuesday morning, will report back once my mind has been made up.
