Haven't gotten to try Infra Arcana yet, but I have tried out Elona. It's a goofy fantasy game set in a standard jrpg anime fantasy world. Kind of cutesy, not necessarily in a bad way. The graphics are better than a typical roguelike...but....read on for my reservations about the game.
It's...hmmm. Hard to describe. It's fun, yeah, but to me, it's not really a roguelike, even though it's billed as one. It lacks permadeath, for one, and wizards are damnably hard to play because the game is geared against them (in most playthroughs, spellbook drops/getting them in shops is rare, which makes your character kind of useless). It comes off more like an off-the-wall and difficult to play japanese rpg than anything. I do enjoy it (its hilarious, and you can die by the craziest things), but I wouldn't go so far as to call it a roguelike. More like a "roguelike-lite." It's got the randomized dungeon/enemy element, and the controls do remind me of a proper roguelike, but it's lacking that fundamental permadeath feature, and some of the races and classes don't seem playable. To me, a roguelike should have each race and each class as something that can be succeeded with, even if it's hard, and wizards in Elona are doomed to fail. But yeah, some of these things don't seem playable. Don't believe me?
You can be a snail in Elona. Or a farmer. Or a tourist.
At any rate, I'd recommend Elona for someone wanting the tone of a roguelike but who doesn't actually want to play a roguelike.
