Really though, my post was not about lambasting Americans (which, by the way, are not the only people who play on NA servers) so much as making the point that Tequatl is not "casual" content in any sense of the word. And regardless of what excuses you want to make about Liadri and Super Adventure Box (being trial and error, temporary) they were still a part of the Living Story and they still aren't in any way, shape, or form "piss easy."
Clearly, trial and error is of course always the starting point. But if any kind of patterns exist in the gameplay, as it does in the DS games, trial and error is quickly replaced by the aforementioned recognition and response. That doesn't mean that trial and error doesn't remain, since new elements come in.
But the fact remains, the question you should ask is not "is there a game beatable without trial and error?", but instead the far more pertinent "is there more to this game than just trial and error?"!
Because, anything that is just trial and error is just that - piss easy. To wit:
1. Flail around randomly until you detect the way past, or more likely, until you detect an obstacle.
2a. If you detected the way past in 1, execute it. Go to 3.
2b. If you detected an obstacle in 1, avoid it. Go to 1.
And how is Teq not casual content? It's in GW2 for ♥♥♥♥'s sake!
