Xenoblade is a JRPG made by Monolithsoft and published by Nintendo. It was a breath of fresh air for JRPS and open world games alike. It was critically acclaimed and is still at the top of my games list.
The game is visually stunning for a Wii game and plays similarly like an MMO in terms of battle strategy. The story is very JRPG and follows that traditional formula throughout the whole game to keep you interested. The music is gorgeous and really sets up the mood for when you are traveling these great landscapes.
If you are in need of a long amazing game to play this summer look no further than this amazing game. It is getting a sequel soon and will rise more in popularity over time.
