It's great to see a lot of conversation on this topic and clearly there is a lot of interest in the legacy gameplay and progression systems.
What surprised me is despite all the demand, talented modders and ambitious overhaul mods there isn't one that simply intends to replace and reintroduce the core systems that made A16 such a fun experience which so want to see.
- Learn by doing
- Action skills
- Original skill tree system
- Original books and skill point book system
- Item quality level 0-100
- Item degradation on repair
- No trader quests
- Big focus on exploration and RNG loot
- Corpses don't decay and can be looted / turn into corpse piles after
- Circular spike traps brought back
- Expanded construction block upgrades brought back (wet concrete etc...)
- POIs that aren't all dungeons
I suspect these are some of the most iconic legacy features folks miss.
I'd love to see these get made into a mod for A21 as I'd love to play the A16 experience with the A21 graphics and new toys.
