Between Teleglitch, Nuclear Throne, Legend of Dungeon, Rogue Legacy, Risk of Rain, Tower of Guns, and a few others, the last year or so has been massively fun for roguelike fans as we've seen pieces of the genre applied to other genres, usually with pretty amazing results.
Prettiest ASCII graphics since Brogue, and I like how the developer puts a lot of thought into the mouse interface as well without dumbing the game down (as far as I can tell).
It's listen along with "a few others" at eg:
Rogue Legacy, as with Teleglitch; tempting at first, but even more so it turns out into a grind dungeons for money type of experience. My take on it.
Tower of Guns, while I haven't had the chance to play this game (since it runs only on Windows), I loved what I saw from the gameplay reviewers. Check out Northernlion's video on it.
If you really want to have a ton of loot, start in original level3, go to the secret boss fight (doesn't always spawn), and spend a few minutes thinking what to leave behind.
I'm disappointed Random Starting Gear is crap. Most weapons are strictly worse than their equivalents using the same ammo. It quickly degenerates into a knife run, because you have no starting pistol until you find a "second" one in level3. The exceptions are sspoon (higher damage per round, perfect accuracy) and fat john (very accurate shotgun with better penetration). These are the tradeoffs you might tolerate into the endgame... although mg3200-drm has a big, undocumented accuracy boost.
Nailguns are questionable even when used optimally.
