Well, Shiren the Wanderer 5 just got an English release for the Vita on the US (bless my US PSN account).
This is a Shiren 1 quality game, and given that Shiren 1 was my favorite roguelike (along with ADOM) it makes me happy.
Basically, these are very discrete, pure, Japanese roguelikes-.
Discrete in that interactions are easily predictable and discrete (you mostly know what's going to happen if you have faced the same situation before. So moment to moment tactics feel very puzzly, while still retaining a surprising strategic depth with resource management, item identification, hunger and other classic roguelike staples.
Pure, because it's a very classic roguelike (with interface improvements, of course). And I mean it. This stuff is closer to rogue than to any other mainstream roguelike out there. Also, systems are incredible transparent and coherent (again, once you learn them). I beat Shiren's 1 main dungeon by using an item that would transform any enemy into food on the final boss. It worked and I ate it. It is unusual to find roguelikes that stick so close to system purity without compensating with resistances and other stuff (all this not really present here. Resistances are also discrete and not that huge).
And Japanese because, well, it's a japanese game. But the aesthetic are rooted in 1995 (it could be reusing SNES sprites for all I know -well, not really but almost-) and there's none hyper cute or hyper sexualized stuff.
So far (beaten the first, easy dungeon) it feels like Shiren 1 but with more pseudo persistent stuff to do between runs (did I mention Shiren 1's progression system might be the best progression system in any roguelike, keeping the hard reset on death but allowing you to store certain items for a future run -but you might lose the in that run, so it's really high reward). So basically expanding on the previous systems, plus a more divided structure, with (I think not that far yet) 4 main dungeons progressively more difficult, plus many challenge and extra dungeons (the real end-game in Shiren game's being a 100% reset 100 floors optional dungeon).
This is really good stuff. Shiren 3 got the series closer to the Pokemon MD games, but this is (so far) a step back into form (and greatness). I think this might be the best roguelike (imho) to come to the market in years.
Edit: It's also out on the EU (they didn't announce release dates, I think, but I was keeping track of the Us version mostly, so maybe it's lack of attention)
