Meteos was Fut 15 Coins clearly designed with multiplayer competition in mind, so it's great that the game gives you the option to take on up to three other players using just one cartridge, through the system's download play feature. You're limited to just a few different stages this way, though, so for best results, everyone should have a copy, and you can convince your friends to get their own by uploading a demo version of Meteos to them if you want. Multiplayer Meteos is functionally equivalent to playing against the computer, though it can inherently be more fun to stomp your friends instead of that damned eyeball.
There's a good amount of unlockable content in the game, too. What's neat is that all the meteos you send flying off the screen (except for incinerated ones) are actually tallied as a sort of currency for the game's unlockables, which include new planets, special items, music, and more. The new planets are probably the most exciting unlockables, since they translate into new riffs on the gameplay. The special items are interesting too, since they include stuff like bombs and hammers that can occasionally fall from the sky during gameplay, helping you clear the path or affecting the action in other ways. Meteos also tracks a ridiculous number of different statistics, helping make you feel like all your time spent with the game is contributing to something greater--especially since certain unlockables are tied to other metrics, like your overall time spent playing, and not just your number of meteos fired offscreen.
