I try not to buy anything on my wishlist during Secret Santa time. This weekend is probably going to be my last major outing before x-mas.
I like to add an addendum to my lists, if you have some game in mind you think I'd like but I don't own, go for it. It might wind up a new favorite and I just don't know because I've never played it.
I always want to add a statement like any N64/SNES game I don't own, but that's just not reasonable to do that kind of work to figure out what I have and don't have.
It's just too hard to make the time or effort to figure that stuff out, especially when you don't have the time to go hunting or shopping in general.
