Personally I don't think patents that are too generalized should be allowed. If you invent a machine that does one thing by one method, then your patent should not be so general that another machine that comes to the same end result by a completely different method isn't allowed. Or in the case of card and video games, I don't think you should be allowed to patent a word so that it can't be used in another game. For instance tapping, what if you had a card game that had a mechanic called tapping that has nothing to do with the tapping mechanic from MtG? Like maybe you could tap a resource card to boost a character card and this moves the resource card to the graveyard. That would have the same name but still be a different effect. Maybe you have a card or board game whereby you physically tap on a card to designate that it is a target or something. If things like that aren't allowed because of a patent, then I think the patent needs to be reworded. As it is now, many games have extremely similar mechanics that are all called by different names and that's just ridiculous.
