Pre Prodction Basic ideas

Many of my ideas evolve around making and RPG hack n slash where you choose your character and go through dungeons and hack at enemies until you get to a final boss. Another idea was to create a zombie survival game. Racing games seem like a fun idea to do also but making smooth movement is going to be hard. there are multiple other styles of game I might explore into looking at story lines game dialogue or even a multiplayer head to head like pong. I feel like all my games are going to be be heavily fantasy based as this genre is always appealing to me. During my experience with gaming i have found that multiple RPG games invest a lot of time developing boss battles giving them battle phases and sequences that when they first come out are never clear on what the best strategy is to defeat it, designing unique effects and abilities has always interest me and this will be my main focus.
