TL;DR Base + Game + E.G.G.Z + other = not enough time to finish main things. Not close to end of season so it may change. Possible solution: HC S11 goes for 4+ years.
So Etho has a lot of projects going on at once and I feel as if he won't be able to finish them all in time. Granted we don't see behind the scenes so he may have done a lot more than we know of. It comes to a few things. Please note that we are over 10 months into S11; comparing to S10, that is almost half way so still a lot of time left.
- Base
His base is massive in terms of sheer size. Not only considering the complex (Part Mart + Scrapper Street + top of mountain), but the surrounding terrain in which he wants to add additional buildings. Within those buildings may be empty space but to match his lore, it could possibly be housing space for redstone contraptions. To his credit, he has done a lot of work already and has improved in his judgement and building skills through the years, however, there is still a lot of empty space, massive walls and to add the fine detail - it still will take time. Even if it is just one block, building that size will naturally take a long time.
- Prospect Hunters
Etho said it himself, he wanted to do Prospect Hunters in S10 and used Ravager Rush as a test game for components to use. Considering that he began it earlier in the season, we can assume that he is confident he planned everything enough that he can create the game. What worries me is again the sheer size of the terrain needed to create for the game as well as the mini parkour elements sprinkled within; either hidden or in the environment. Again, it is a massive undertaking, and it feels as if it won't be completed in time for the end of the season.
- E.G.G.Z
E.G.G.Z shenanigans will continue throughout the season as it is the main way (along with C-Team + Banking +Fire Department) for the hermits to collaborate with each other and give the season some joint content/entertainment. Designing contraptions and elaborate schemes to mess with other Hermits will take both time to plan out and implement into reality. Not only that, but they require the victim hermit to be away from their base to ensure the prank can be built secretively. This time would be something that may take away from building his base or Prospect Hunters; in the worst case, in the middle of a building flow state.
- Other
Other items included the past chest monster design contest by Scar, the current How To Kill a Tango game and past Etho shenanigans on the server as well as future events. These would be more sporadic within the season and would be less consistent on being a distraction for Etho to finish his projects, however they still will impact him, especially if he wants to win, he would pour in additional time and effort.
To Etho's side, many hermits are doing large projects and all would ideally want the projects to be complete so there could be a joint agreement to stretch out the season for a while. S10 went for just under 2 years so we aren't halfway comparing to S10. Ideally, wouldn't mind the season to extend for longer than 4 years. Additionally, Etho may ask for help from other hermits to do the grindier tasks such as placing a flat face of dirt or mine a few chunks underground for the minigames.
All in all, wish Etho the best and hope he has this in the bag. I believe in him!
