I see "keeper" thrown around quite a bit and I've got a couple machines I would call keepers as well but I'm curious how many of you have gone on to sell a game that you considered a keeper at one point? I thought TAF was a keeper but it turns out that Luci was more enticing and I had to sell TAF to get it. Some people seem to have enough space that this is less of an issue, but many of us have limited funds or space and thus at times we're forced to sell the ones we love for ones we love more (Or other times those keepers turn out to lose novelty, just over a longer time span). I figure my collection is small enough (5) that I will probably trade out most of them down the road but right now in my head 3 are pretty much keepers that I'd like to hold on to. I can see that changing in 2 - 3years though haha.
So.. who's sold what was once a keeper, what was it, and why did it have to go? Did you pick another up down the road? Regret you let it go?
