Right now, number of votes is like this:
Xenoblade Chronicles: 15
Lost Odyssey: 9
Suikoden II: 8
Trails in the Sky: 7
Dragon Quest V, Xenoblade Chronicles X, Ni no Kuni PS3: 4 (I'm adding a vote to DQV because someone says I had to play one of them, though (s)he didn't specify which one).
Pokémon Soul Silver, Mother 3, Suikoden, SMT III Nocturne, Nier: 3
Bravely Default, Mega Man Battle Network, SMT Digital Devil Saga, Digimon Story Cyber Sleuth : 2 (the people who voted for MMBN said 2 and 3 are the best ones though)
Dragon Quest IV, Rune Factory, The Last Story, Final Fantasy Tactics (WofL), Valkyria Chronicles, Fallout 3: 1
I actually ignored my own rules -.- and registered a vote even when some of you mentioned several games. I'll wait a few hours for EuropeGAF to see my thread but I have to check how much money I have in my Nintendo account because it seems that I'll play the digital version of Xenoblade Chronicles.
