In the past few months we saw some projects trying to bring Monkey Quest, our childhood game, back and that's a incredible thing because that shows that the game community isn't dead after almost 4 years of the game closure. People like Breadloaf, Aberidius and VICTTI did give us hope on bringing back MQ. They showed us that the game can return with our own look, our own updates and the old style that everyone likes.
After MQRv2 (VICTTI's) people started to think that working on a such a big project is an easy thing to do, but it is NOT. The game had not only the scripts in the main .dll file but it had thousands of scripts on the Asset Bundles(an encrypted update system that Unity uses to give new patches to a game without updating the actual game version) and these scripts can't be decompiled in any way. Not only it need new scripts, it require a good programing language knowledge, since the game had a lot of diferent mechanics. Some of the scripts that shows some of the mechanics has more than 500 lines of coding that require others scripts to work.
Right after v2 died, Trekkbee showed up with his own MQR project. In the begining they had 2 developers: Trekk and VoidEnemy. The problem was that, according to Void, Trekk wasn't working on the project directly. He was only giving tasks to Void. Enemy showed to the communtiy that Trekk asked him to finish up the first alpha build in ONE month and said that he wanted that version with all the progress that VICTTI's MQR had. The development stopped right after that because Void left that project and Trekk just vanished from Discord after people found out about his age.
One of the biggest problems with that project was not only the lack of communication, but the lack of maturity with the project. I was part of the Trekk's Discord server and they just decided that MQR should have a new tribe, out of nowhere. It had no context or story to add that new tribe and it didn't have ANY real progress on the game.
If you know scripting enough to start this project, you still need animation knowledge. Just like the scripts, there's no way of getting the animations out of the Asset Bundles nor the old client. The game had thousands of animations. The monkey that you play with has more than 15 animations + emotes.
The last and the most important problem that the Monkey Quest Rewritten project should face is Copyright. It is true that the Monkey Quest trademark expired but all the files that you use that comes from Nickelodeon contains Copyrighting. Basically if you make your own MQR project and DON'T use ANY of Nickelodeon files, you are most likely safe to pass through illegal issues.
TL;DR: MQR requires MATURITY, SCRIPTING AND/OR MODELLING AND ANIMATION KNOWLEDGE.
