A few examples:
Did not like X-Com and I thought the Rabbids games were only ok. Mario + Rabbids is pretty fun though.
I have no interest in playing any Might and Magic game. Heroes of Might and Magic 2 is one of my favorite games of all time. (HoMM 3 is great too.)
Only played Skies of Arcadia for about an hour before my Dreamcast broke, but I didn't really care for it based on that. I really, really love Valkyria Chronicles.
Honorable mention goes to the Dynasty Warriors games, which I do like, but are nowhere nearly as good as either Hyrule Warriors or Dynasty Tactics.
