Hard time deciding..help a fellow gamer out?

Before I start, I realize probably half of you are going to say, "Dude, we can't decide for you, do what you want." Okay, with that out of the way, here is my dilemma! I know that, without a doubt, I will be buying Mafia II. But, there are two series that I have been wanting to start playing. That would be The Force Unleashed Series and Kane and Lynch. Being that Star Wars and Kane & Lynch both have sequels, i'd obviously like to start the series from game one. I believe I can purchase both games for around a total of $40.00 at Gamestop or any other retail store. I figure, I can start and finish each game, along with also completing Mafia II. Come Christmas time, I could ask for SW: FU II and K&L II and they'd probably be somewhat down in price, who knows?

So, i'm asking that you cast your vote in the poll. This is simply just to see what the majority group would do and would somewhat have an effect on my final decision. I really don't know whether or not I should save the 40 bucks and just wait for Mafia II, or if I should go along with my plan of starting the two series that i've really been wanting to get into and being able to continue both stories in a couple of months? What would YOU do?
