Experimental IFDB feature: Finding games with similar tags

I’m not sure what the plan is, other than gathering feedback from people and discussing it. @dfabulich?

An issue I see with some of the results is a tone mismatch between the original game and the result. Maybe having some standard mood/tone tags could help, and maybe sub-genres (e.g. dark fantasy).

I was thinking we should probably figure out if we are going to overhaul the tagging system or not, because that could affect this a lot.
