Guys, guys
Wizards resurrecting dinos to fight aliens fits every genre perfectly
An RTS or TBS, you play as the magically imbued dino-squad, going out to fight the alien menace.
An FPS, you play as one of the sauropod squaddies, or one of the wizards. Over 600 unique weapons, each of which can be combined with at least 12 other weapons or dual wielded for tactical strategicness.
An RPG could play like either the FPS or the TBS, but with more in-depth inventory and leveling system (including fully customizable armor, down to fingers on gauntlets), and a more player controlled pace.
A fighting game could feature tons of both pre created and randomly generated characters, any combination of dinosaur, human, soldier, wizard, alien, mutant bioweapon, android, or zombie. Combos would be long and intricate yet also intuitive and context sensitive button based.
A city builder involves both managing a city to produce for the war effort and find places for the dinosaur and wizard veterans in society. Additionally, tycoon games for finding employment for said vets and ways to profit off of magic and dinosaurness.
A roguelike is quite like the RPG, and involves doing single-handed stealth missions against the aliens with your elite dinosaur operative, additionally allowing you to skip the main story and free roam like DF, chosing instead to use your magic velociraptorocity to combat the evil mole-people under the earth, who you created yourself with the intuitive dynamic puzzle-based crafting system.
A racing game is set either in an alternate universe or along one of the many clandestine fronts of the interplanetary war, involving a covert treaty system to win or lose battles based on the results of kart races.
A train simulator would involve setting up supply lines for the defense of earth, as well as possibly setting up trains to intersect alien landing sites so as to run over as many aliens as possible.
