There are a few of us around. Last year I joined a group in Westhill, but my shift schedule soon put an unfortunate end to that. As for a gaming store, the Waterstones on Union Street had a few bits last time I checked. There's a Forbidden Planet, and Asylum Games. I've never visited the last, but I understand it's mainly a comic shop.
On the plus side, the daffodils are now if full bloom and look gorgeous. And Aberdeen is one of the sunniest places in the country, though definitely not the warmest!
PM me when you get here.
