Well, this came entirely out of left-field. The horribly titled Implosion: Never Lose Hope
is a fantastic Diablo-style action RPG with an sci-fi anime aesthetic. It looks absolutely amazing, the combat is quick and responsive, the sound and voice work are great, and it's an absolute blast to play. It's broken up into a mission structure, with each mission taking 5-10 minutes to complete, so it's perfect for playing in quick bursts. There's a huge variety in combat, with light and heavy melee attacks, dodges, special abilities, and a ranged attack that is mapped to the same button as melee. Sounds like it would be a disaster, but it works remarkably well. You can't just button mash, as special moves are activated by pausing between taps. It's a cool addition which makes combat feel much more involved what you normally see. You can upgrade your character's mech suit, there's a whole host of achievements and unlockables...it's all just a very solid package.
