Those are definitely not games to play in Japanese unless you know how to read the language, A-Train particularly -- that game is all about menus and charts and stuff after all, and it's mostly in Japanese. SimEarth looks slightly more playable, but still would be frustrating, since there is text. You'd need to memorize what every icon and symbol represents. Save yourself the frustration and play it in English, if you want to play SimEarth. You'd need to play it with an English-language manual or guide for sure. The PC version of SimEarth came with a 220-page manual that explained everything, for instance... I know the console manuals aren't nearly as thick, but that'd probably make the game harder to figure out -- it's a complex game.
