I hear you. I live in Newmarket and just bought a townhouse for $350k. This would be impossible for my family back in Ohio to understand, since there, an expensive house would be around 80k.
If you have so much video game related stuff that it would make a dent in your liabilities, then yes, I would sell. Prices for much stuff is relatively high right now. It sounds like you have a lot of stuff just sitting around that will never get enjoyed. Sell it for sure.
