It's been about two weeks now since I got my 3DS XL and about a week since I got most of my games and I have to say I already amassed a backlog of 3DS games to play.
So far I've only been playing two games; Animal Crossing New Leaf and Project X Zone.
Project X Zone was actually the first game I got the system and it's the digital version. I put about 20 hours into it thus far and I am loving every minuite of it. I highly recommend this game to any rpg/strategy fan or anyone that loves the cast of characters
Animal Crossing New Leaf, been playing it casually, just like it's meant to be played and I am still learning it. Luckily I spent hundereds of hours on Animal Crossing Wild World for the DS, so I was able to adapt to this game just fine and it looks like I will be spending hundreds of hours in this game too. I don't know how long I spent on this game in total so far, but I'd average somewhere between 10-20 hours.
Then there's the backlog of games. I haven't even started these yet
Monster Hunter 3
Harvest Moon: A New Beginning
Heroes of Ruin
Resident Evil: Revelations
Castlevania: Mirror of Fate (digital version)
Kingdom Hearts 3D
Legend of Zelda Ocarina of Time (digital version)
There are several other games I plan to purchase before the year ends. Two of the main ones are Pokemon X/Y and Legend of Zelda A link Between Worlds. I also plan to pick up Fire Emblem sometime soon too (maybe when I complete Project X Zone)
