Wait a second...FE Sacred Stones? How?

OT: 

1) FE: Awakening: 65:45
2) Etrian Odyssey IV: 65:30
3) Shin Megami Tensei IV: 64:35
4) Virtue's Last Reward: 45:33 
5) Pokemon X: 43:30
6) Zelda: A Link Between Worlds: 20:15
7) Mario & Luigi: Dream Team: 18:13 (Still need to finish it though)
8) Dillon's Rolling Western: 12:46
9) Super Mario 3D Land: 5:11 (yeah didn't like the game)

Didn't realize how long Last Reward is...btw where is my 3rd game!?

Edit: I just noticed that the in-game clock for Mario & Luigi says 12:30...wow I tend to leave my consoles unattended for way too long xD

It was one of the Ambassador games. Unless you mean how he played it that much....though it does have a lot of replay value. I started replaying it last year, but got distracted with some other game.

My Top 10:

1.) Tales of the Abyss - 169:17 (216 times)

2.) Fire Emblem: Awakening - 166:50 (229 times)

3.) Animal Crossing: New Leaf - 148:21 (206 times)

4.) Shin Megami Tensei IV - 94:51 (126 times)

5.) Zelda: Ocarina of Time 3D - 81:44 (135 times)

6.) Pokemon Y - 78:39 (65 times)

7.) Golden Sun: Dark Dawn - 70:27 (144 times)

8.) Pokemon Conquest - 65:55 (76 times)

9.) Dragon Quest IX - 37:47 (54 times)

10.) Kid Icarus Uprising - 35:42 (41 times)

I have a feeling Animal Crossing is gonna to keep climbing, since I play that semi-regularly. I still have post-game stuff to do in Pokemon and Fire Emblem, and I plan to do a New Game+ in Shin Megami Tensei sometime, so Tales of the Abyss will likely be dethroned this year. It's still interesting to see that at the top; I consider myself a much bigger fan of FE than Tales.

Funny enough, my in-game clock for Mario & Luigi is about 30 or so hours more than the time on my Activity Log.  I think it's because of how long I keep the game in sleep mode.  I'm thinking the game sometimes counts my sleep time as playing time.

I would have to stop playing Bravely Default to check that, so maybe I'll get back to you on that. I know Monster Hunter 3U is over 400 hours though.

Pokemon Y - 50:23
Mario &Luigi: Dream Team - 38:17
SMTIV - 23:49
FEA - 22:13
Weegee's Mansion - 19:08

Pretty pathetic compared to a lot of you guys, but I don't have much time to game. And when I do it gets spread out on PS360, PC and PS4.

I was talking about how he got the game. I always forget about the ambassadors program, those guys got some really good games...kinda regret not buying a 3DS early haha.

1) Animal Crossing New Leaf 394:33
2) Pokemon X 158:30
3) Streetpass Plaza 132:25 (I was a bit shocked at this but my Streetpass hits sits at 3140, plaza population 2100 and I own the DLC expansions)
4) Fire Emblem Awakening 117:27
5) Resident Evil Mercenaries 75:36
6) Resident Evil Revelations 71:15
7) Fire Emblem Sacred Stones 57:57
8) Super Mario 3D Land 53:15
9) Mario Kart 7 49:33
10) Pokemon White Version 2 45:23

Total Play Hours per year:
2014 - 114:48
2013 - 856:47
2012 - 435:49
2011 - 262:03

1hr by train to work, 1hr by train back again really adds up. Then I used to play an hour of Animal Crossing before bed to wind down at the end of the day.
