@Hurricanerice and @F0xBirdmansBFF, I have plans to deal with lag and performance regarding the different devices players may use to play my game. I could also teach you if you would like.
@Megalodox_Official, Roblox Studio is designed to give you all the tools you need in order to create a great game, including, ways to generate graphics like Call of Duty, Dying Light, and Ark Survival Evolved. There are also plenty of action games on Roblox.
When it comes to creating something, you want something new, something unique, and in the past 7 years on Roblox, originality and uniqueness seem to be something Roblox is lacking. People say that Roblox is a children’s game, which may be true, but it is the developers of Roblox who are the ones to fix this, but it just seems that majority developers are too lazy to make anything worthwhile.
One thing I have noticed is that developers are often good at developing and bad at game design or great at game design and bad a developing, therefore a developer will create a game like Adopt Me or 3008 where the game is pretty straight forward, but not much to do, like what do you do with pets in Adopt Me after you get one? Another thing I have noticed is how developers often rely on other developers for ideas, for example, look at these Roblox game names:
- Goal Kicking Simulator
- Mining Simulator
- Bubblegum Simulator
- Lifting Simulator
- Bee Swarm Simulator
- Roller Coaster Tycoon
- Clone Tycoon
- Tropical Resort Tycoon
I believe good graphics can bring a level of uniqueness to my game as well as others and make them stand out. After all, most games on Roblox have very poor graphics.
Your average Roblox graphics
Adopt Me:

Whacky Wizards:

Brookhaven:

Jailbreak:

If all goes well, my game should target all ages, like Minecraft, not too simple, so older audiences will get enjoyment, and not too complex for the children, but I guess I should keep it on the children side figuring how kids are the majority audience.
