Mortal Kombat X is many things. It is mechanically refined and stylistically muddled; it has a sometimes unpleasantly violent, sometimes charmingly hammy commitment to the traditional fighting game template. It has thrust the series forwards and succeeds in delivering nuance while offering a welcoming genre gateway for inexperienced players.
It's easy to forgive Spintires: MudRunner exactly because it has such an eccentric charisma. It should be dull. It should be frustrating. It should be prettier. But it has its own strange beauty and offers something refreshingly unconventional in the driving genre.
Rival Megagun may fall short of the standards set by genre masterworks like Cave's Ketsui, Seibu Kaihatsu's Raiden Fighters Jet or Raizing's Battle Garegga. But those are some of the finest pieces of game design of all time, and failing to meet their lofty standards doesn't stop Spacewave's creation being a tremendously fun and rather distinct shmup that really does offer something fresh, and serves as a great demonstration of the Switch's multiplayer prowess in the process.
