Roguelikes are relatively primitive, cruel types of role-playing games, often intimidating to the newcomer. Legends of Yore, thankfully, is a lot more accessible.
It's a roguelike (definition here) for the iPhone and Android that's trying to make things a little easier on the mobile adventurer by limiting the number of stats and streamlining things like movement (just tap on the screen to move there) and combat (tap on the bad guy to attack).
The first thing that will grab you, and the game's key draw, is some lovely pixel art, which is simple to the point of charming, without coming across as crude. Upon first booting up the game, you'll probably just want to wander around taking in all the scenery and checking out how cool the dungeons and bad guys look.
Fans of old-school Zelda games lured in by that, though, be warned: it may be a more accessible roguelike, but it's still a little on the harsh side, lacking in manual saves and being more than a little short on guidance or hints on what to do or where to go next (though it should be noted the game is in a kind of perpetual beta, continually being updated).
If you don't mind those kind of shortcomings (and some annoying graphical glitches with the text), Legends of Yore is a great time-killer for the adventuring phone owner, especially since it's free (it's also playable for free in your browser at the game's website).
