I know its probably not the most popular request, but limit the dropped guns in there?
Dropped guns in an instance like this at the rate they are dropping will kill what little markups hunters or crafters can get out of drops found by playing the game as it was designed through hunting and crafting.
As it stands I know several people who simply farm the 10 minute instance for guns that generally take hundreds to thousands of peds to cycle to maybe drop a similar gun in loot. These people have stopped cycling thousands of peds a day to just a couple hundred, and contribute nothing toward the economy that needs much help already.
This doesn't even factor that those people no longer are buying guns as well, creating a bigger problem with being able to sell crafted/looted guns, because they don't need guns to run an instance.
We have 10 million (L) gun options and crafters and hunters continually get the shaft when it comes to markups for these items. At what point will we ever say.... this is enough weapons to choose from?
Its bad balancing in my opinion, and will have real negative effects for people who rely on markups...something critical to success in this game.
or maybe just make the guns that do drop in there only work in there since this thing is more or less just a clone of the hub and there's lots of stuff related to the hub that only works in the hub... maybe also perhaps allow some guns that drop here to work inside of the hub itself or similar places, etc.
Also, suggestion for more maps is a good one... if it's the same exact maps those that learn it well will get faster than the rest who don't practice as often/can't afford to practice as often, etc.... put in like 20-50 maps, and make it so you can only play on each map variation once per day, and it'll randomly assign em to you... so you could play multiple times a day, but not on the same map more than once a day.
Otherwise make it limited to only so many 'turns' per day max similar to the max you have in compets... only one sim per day per map limit seems fair.
While it does make sense from a business perspective to want to be greedy and allow folks who pay to win by letting em play same instance 3000 times a day, that kinda defeats your whole premise of making it a place where everyone has the same chance that you are advertising the hell out of on this thing.
Also, perhaps put in more ways to loot, etc. Instead of one way to loot at the very end, do like one loot box place every 1/4 of the way through so that those that don't make it to the very end at least get something back for participating. Make those loot places 'auto looted' or at least put the box somewhere easy to find next to a doorway between sections or something so that folks won't have to go looking for it too far off of the main path...
Last but not least... this thing is a 'global' thing supposedly... no avatar can sell things in the 'global auction' yet... perhaps you can allow us to start selling in there but only for items that only work in the sim and nowhere else? Maybe make items sold in there have no auction fee? Sounds crazy, right, maybe, but you removed the monthly rent on shops long ago, which also probably seemed like an impossibly crazy idea before it happened...
Also, related to that global auction idea... create a token to buy items that work in there, similar to the lime green ones in the hub and put in a shop npc at the beginning before you aggro anything and at the end before you exit that both allow you to use the tokens to buy stuff in there... also put a shop that takes the tokens out in real game somewhere that you can access without going in to the sim... and allow these tokens to be tradeable, but only in that feeless global auction mentioned above.
Allow bid increments on the global auction to be at pec level instead of at ped level, but make it so auction ends at actual end time, and doesn't add 5 minutes like regular auction. Allow us to put in a buyout though so that we aren't handing everything to auction snipers.
Make it so you get one of these tokens at the beginning auto looted so you at least get something to show for going in, even if you don't kill one mob, just as a sort of reward for at least trying. Allow the shop at beginning to be checked out before timer starts, and only start timer after first aggro... Allow shop at end to have the most uber items for in sim use only, but make it so that you only have a minute to buy there or browse there before you get kicked out of the sim... the one in the main game before you go in the sim should have ok items, but that are lower end stuff that isn't as useful than the shops in the sim... perhaps limited to armor in the one outside of the sim, lower level or damage weapons in shop at beginning of the sim and higher damage stuff in shop at end that you only have 30 seconds to a minute to browse before sim ends... all items that you can only trade inside of the 'global auction'...
these shop ideas are probably go against the idea/theme that it's equal in there for everyone, but at the same time, since there's a shop in the hub, it doesn't seem logical to do something similar on this thing... to reward those that go in and try it over and over... as far as the ladder goes, maybe do different ladders for those that use none of the stuff from the shop, and another for those that used items, etc.
