My collecting interests are quite different so it's hard to compare. With that said I have recently discovered that less is more. For me anyway. Of course we all dream about having enough space to warehouse every game we could possibly be interested in. For me though I came to the realization that the last one in is always the most fun. I find I'm most happy finding a cheap project, cleaning it up and playing the crap out of it for 3-6 months. Cut it loose and start again. Having constant turnover keeps my short attention span interested. There are a few that I have sold that I miss a bit but if those titles turn up again affordably I'm not opposed to revisiting them.
