Damn I wish they would sell in Europe directly. Ordering anything from Analogue would have ridiculous shipping costs and customs duty so I never got around to ordering the Pocket either. I know there are cheaper options especially for game boy hardware but Analogues is just so sexy.
If you factor in every Japanese game in existence this statement will crumble really fast. Your examples are both Nintendo games and they have particularly high quality standards and a focus on fun gameplay (ignore the water temple in Ocarina of Time).
