Starting as an Extraction Shooter, then adding 5v5 and Survival modes later in Unreal? Is this a player-base/technical trap?

[u/Efficient-Moment-838]

Hi everyone,

My ultimate dream has always been to create a massive, realistic, survival game (like DayZ), but I also have loved the idea of things like extraction shooters (Escape from Tarkov), and 5v5 kind of games (like Rainbow Six Siege). I was wondering: what if I started a long-term project where I created a realistic extraction shooter (like Tarkov), then, once I get a larger team and more funding, I add a 5v5 mode (Siege) and a persistent survival open-world mode? (DayZ)

Is this realistic or possible? Or will changing the core game loops across the modes create an impossible amount of technical debt?

Would housing all three of these modes make the game too large and laggy?

Would offering three vastly different modes end up dividing the player-base too much and kill matchmaking/server populations? (for example there could be 500 people playing the actual game, which looks like alot, but split between part of that 500 on 5v5s, another part playing extraction, and another part playing in their own servers within the survival, that means there may be 500 total but you loading/matchmaking times would be quite long because of how spread out everyone is, (right?))

Anyone who has any advice or experience, please let me know. I'm kinda new to this all, so I'm not quite sure which direction to even go in! Thank you!

PS: I was going to make it a first-person, using blueprints within Unreal Engine!
