"What do you generally think of Minecraft mods?"
Mods are often good things in video games. It adds content that people don't have but want. Personally I don't use mods that add content, but that is because I am satisfied with the vanilla game. People who mod are just people who want other things in their game, and if they can get it they will stay, so mods are good for both the game and the players.
"How do you see the effect of mods on your Minecraft gameplay experience?"
If people add specific mods for their game then it is there to enhance their gameplay (in a way which the vanilla game can't).
"Can you also describe any possible negative experiences with mods on your Minecraft gameplay experience?"
If people use the mods they want then I don't see it being something negative, but it can lead to lag.
"How do you hope / modding will develop in the near future for Minecraft or other games and why?"
For Minecraft I hope that modders will update their mods more frequently in the future, and also that more mods that enhance vanilla is developed. I also wish for Mojang to work more with modders for Java Edition. I don't keep up with modding anymore so I don't know how it will develop.
