I'm sorry for not being specific, guys. There's some people who don't know Inazuma Eleven.
As my friends explained, I'm annoyed off because we (America) only have the first game in the series (from a total of six main games).
The first 3 Inazuma Eleven were released for the DS, with poor graphics (left on the image). Then, the Nintendo 3DS received a series called Inazuma Eleven Go, with top graphics, as the 3DS deserves (right on the image). Several years have passed on the story, you can compare that to Yu-Gi-Oh! and Yu-Gi-Oh! GX or Digimon Adventure 1 & 2. The game didn't improve only on graphics, but on gameplay and mechanics too!
Well, all the games were released on Japan (of course, it's a japanese game)... but what makes me angry is that Europe is receiving the fifth game (the second on the 3DS series) and... do you wonder what America have? A REMASTERED VERSION of the first first Inazuma Eleven from the DS, released only on the 3DS eShop!
YEAH! YOU READ RIGHT! We didn't receive a single 3DS Inazuma, and we don't even have a retail version of any game! ¬¬
