Revolgear Zero

While Revolgear Zero takes a minute to learn, it's a big fun shooter that's more interested in being played than punishing the player. Beating it on the normal difficulty isn't that hard, which I discovered when the gameplay systems clicked and I blew through it with double-digit lives left over, but harder difficulty levels and unlocking Boost Mode (same levels, faster energy regeneration) give the game plenty of replay. Arcade shooters tend to be known for their difficulty, like the excellent Sektori, but approachable games like Revolgear Zero are perfect for introducing new players to the genre while having enough depth to its systems to make the harder difficulties worth exploring and repeatedly dying in for more experienced fans.
