Tokimeki Memorial implications

tokimeki memorial 2 -> tokimeki memorial
tokimeki memorial 3 -> tokimeki memorial
tokimeki memorial 4 -> tokimeki memorial
tokimeki memorial girl's side -> tokimeki memorial
tokimeki memorial girl's side 3rd story -> tokimeki memorial
tokimemi memorial only love -> tokimeki memorial

Reason: All part of the Tokimeki Memorial series.

I'm also wondering if there should be a tag for the first TokiMem as well. As it is, the first game and the series tag are the same.

Yes, use tokimeki_memorial_1 for the first game.

Done, plus tokimeki_memorial_1 so you can fill that out as appropriate and it'll implicate the base tag.
