Ummm. I don't mind CoD, but it seems you are trying to make it out as the best game ever. It isn't. Baldur's Gate is (Just ask game Devs). It is actually stuff like this that makes me not play CoD, other than the fact I hate how it plays: People who don't seem to get it isn't the best game ever.
Graphics. Nowhere near the best. They are bearable, but not what I would call great. Other games have far better graphics than CoD, the most well known of which would be BF3, though it is not the only one.
Aesthetics is not how real it looks, its how the art design is. Mario and Final Fantasy's aesthetics are fine, they do not try to look real and it works well. Personally, a realistic looking Mario would creep me out. No game I have seen has anything it should take from CoD in the aesthetics department.
In addition to that, quite a lot of games controls are smooth and easy, hell, they are designed to be. Play portal. It plays smoothly and easily too. As does Pokemon, Battlefield, Halo, Starcraft 1 & 2, Warcraft 3 and most games out there.
Mario also does not have awkward gameplay. Its smooth and easy. Run forward and jump over things. Land on them to kill them. That is the majority of Mario game gameplay. And yes, there is limited tactics and strategies, but CoD has that same problem. Play Starcraft 2 or any Total War game or Civilization if you want a lot of tactics and strategies. Compared to them CoD is like that snail game I played where the only thing you do is move forward.
CoD is a good game, for those who like its gameplay style and can stand its fans, but it is not the best. I don't hate it, but it is not what all games should strive to be more like.
