A game like Spore where you play as The Flood from Halo
>start out as a single spore drifting through the air
>infect a host and game turns into "Stubbs the Zombie" type single player game where you go around infecting other people, evolving and acquiring new traits
>once you complete the "city" stage the game turns into an RTS like command and conquer where you command big armies of infected to defeat the military and take over the entire city. The playstyle of your army is determined by traits you picked during the single player stage (like having slow but tanky infected, fast but squishy infected, or even large tanky infected that are low in number)
>once you take over the entire city the game turns into a 4x like Civ where you spread across the entire world, which changes again based on traits you chose in the previous stages
>once you take over the entire world the game turns into Stellaris or Battlefleet Gothic where you go around infecting other planets and defeating non-infected fleets
>once you're at this stage you can choose to either infect planets and repeat the RTS/4X stage (stealthy infection, more hands-on approach) or bombard the planets from orbit (takes less time but requires more resources and fleet power)
>end goal of the game is to spread across the entire galaxy and infect every planet
>once you reach this goal you can choose to end the game, or you can send a lone ship carrying an infected payload out to infect another galaxy and start the entire process over, keeping all your traits and beginning a new game+ playthrough
