Gaming industry is bigger than music and film industries combined. Designing a high quality game costs a LOT of money.
This is probably why there are a lot of people developing games right now and make them "reminisce" some of the old times or the current generation experience during their early days.You are probably talking about indie games, which are low-cost games.
A played an indie game recently which a liked a lot, Hollow Knight, it was partially costed by $57k
Still to produce something like this is a feat, and developing it with the blockchain tech with collectibles would be nice and would really give value to the time given by the players.A played an indie game recently which a liked a lot, Hollow Knight, it was partially costed by $57k
You need talented designers to create a beautiful game, you need to create nice sounds/music, it is not a one man task. You need years of development and some amount of funds to hire people.
I do believe that and need to be with someone with a background on UI/UX design and sound production for that. Probably the best way to approach this is to create a company and ask for funding that support startups etc.I think that for a blockchain game you will also need some blockchain developers (solidity). There are some guides on the web, such as https://cryptozombies.io/
I did find this resource and I managed to finish the first chapter "Making the Zombie Factory. Now I'm on to the next lol. Maybe this could help me visualize and internalize what I can develop with this.
