With the way Playmaker works you can use it to make just about anything. This sort of question gets asked a lot and its a bit of a weird question when you know what Playmaker is and what it is used for.
Basically it's a tool that lets you design subsystems of a game with a bunch of generic "Actions" which are just very modular scripts you can use in combination to do awesome stuff. Almost anything, really. The same actions that make a Top Down Shooter could be used in some fashion to make an FPS, or RTS. Mouse Picks, Raycasts, Collisions, and basic state transitions driven by conditional logic are all basic features accessible in Playmaker.
If you're considering a Resident Evil style FPS/3PS you might want to know that this is extremely ambitious for a beginner.. as in plan for at least a year worth of development after you gain a basic understanding of Unity, design fundamentals and good practices.
