Hi!
I like the general idea, but I'm not sure about it as a roguelike game, since the basic concept for these kind of games are the repetitiveness of the game (or sections of it) with randomly generated rooms.
As you describe, it seems more a RPG or an action game.
Think about how Binding of Isaac, Hades or Moonlighter works.
Another point is about "different illicit substances/paraphernalia can power you and your weapons up". I see the point of making something different, but use drugs as power up could have a negative impact on the public opinion playing the game, as it seems they are not used in a parody way.
Last think, is it going a project made by your own or joining with someone else?
I am open to the the paraphernalia being toned down a little bit, but i do a like a cheeky reference (as much as a nerdy demographic can handle). i dont think i want it to be RPG - I just meant the "worlds" as in dungeon art style like below
Dungeon 1 is a suburbia style dungeon {streets, houses, delis) and bosses can be band mates parents and the boss level is the house u go to at the ned of the level.
Dungeon 2 can be house and a final train station at the end, boss is police or train ticketer and u fight him on a train level on the way to the city which is dungeon 3
Dungeon 3 can be the ciry on the way to a pub location at the end. boss is the promoter/owner/dealer.
I think the repetitiveness is good, cause partying and playing a new show happens EVERY WEEKEND! (maybe each run u do can be a different weekend on a calendar?) each run after u beat it can be a new set or song u are trying to play at the end boss? I dunno. it could be cool. Does that make any sense?
As far as getting started on this myself. What should i plan first? story? level design? character design? weapons and damage systems?
I'm not 100% exactly sure of the work involved in a project like this, so I am open to being in a team as it may require skills outside my expertise or what I can outsource.
Thanks guys this is appreciated so much!
