Completely different games, really not many similarities, if any.
I understand why people like TNA and while I would play it on location I can't see buying it to put into my home. TNA is a sweet looking game but I gravite towards a different style of game. I prefer deep objective based ruleset games with a lot of toys / mechanical features, lots of animation work, etc, so that's why I went with Dialed In for my next game.
