The problem is you have such a nice variety of games now and only so much time, so how much time can you give to that lower pin? They are priced that way for a reason. There are lower Stern games that I personally enjoy and put time in on though - I own RCT and really like it, I had a TFLE and enjoyed it also. I bought them at fair prices though.
I would go in with a gameplan to buy whatever comes up locally as a deal and play for a while and swap later on. B and C titles sell if the price is fair. So $6200 GOT LE or $4300 GOT pro $4200 Kiss Pro, $3800 Avatar, $4000 TFLE, $3800 Mustang etc.. It is hard to put these above SM though. You already sold SM for a reason though right?
