First game idea is already made and does not gain as much traction like before from the veterans.
Second game is… mildly interesting and could fit a larger audience. It’s a social game and does require more thorough thinking about how the game loop should be.
Third game is repetitive gameplay and does not appeal to the player after to some extent, it’s a linear gameplay loo, unless there is some other mechanics that is unique for the game.
Fourth game has already been done during 2016 or 2017. I don’t remember exactly where the game has gone, but you started at an airport where you could go to different landmarks of the countries, like The Great Wall of China.
Fifth game is ambiguously done. Apparently there has been plenty of survival games on an island, although it’s up to your game design to decide how it is different ffrom others.
From al of those ideas I recommend the number 5. It’s already been done alot of times (for an example booga booga), do my favorite types of games are tower defences and sandboxes. If you listen to me I recommend you the game number 5.
Sounds very interesting, but don’t force Rthro on everyone and give them stupid looking morphs. Just leave the characters looking normal and add customization.
I’m thinking idea #2 has the most potential. It’s encourages social behavior, it appeals to a lot of players, and as far as I know, it hasn’t been done before on Roblox, and even if it has been made before, make yours better.
