Well Willard is at its core an RPG rather than your defacto RP server that every other hl2rp is. Offering a wider variety of skills and leveling systems to define your character and its abilities rather than just having your attributes and very little info to base your characters design on. Also, rather than starting out as generic bluesuit number 242555, you actually get more customization options to your character than what some other hl2rp servers allow. Most servers run on default frameworks and thus have little customization available to their users while Willard continues to modify the framework to suit its needs.
Ontop of that, we utilize a special TBC system which stands for Turn Based Combat, something which you can't find on any other hl2rp servers. A new system developed back in 2019 after the 10000000's of discussions around S2RP, S2K and S2M. Since in the end all 3 of those has their flaws and TBC was a new system replace them. Of course, over time we have found a mix of S2K and TBC works best for the server mainly because TBC in large fights was a slog of a fight and thus far too slow. Faster than S2RP, but far slower than S2K fights.
Willard designs alot of its systems and gameplay around giving the player as much freedom as it can offer as most servers you normally have to rely on Admins to do pretty much anything simply because there is no simple UI for you to do anything yourself. Such as crafting an item. Normally if you want to make a pipe weapon in normal hl2rp you have to:
1. Check the server has such a weapon
2. RP finding the parts (Admin supervision required)
3. RP Creating the weapon (Admin Supervision required)
4. Spawn the weapon in (Admin only)
5. Use it in combat (Some servers need admin supervision for fights because ya know how players get when death is involved)
In Willard it changes to simply: Make it yourself with the materials and crafting UI, no admins required at any part of the process. Everything is findable pretty much and lots of items are craftable for ease of access. Willards core concept is to basically offer more power to the players vs needing staff to hold your hand like some other hl2rp servers seem so fond of.
Think that is pretty much all I can think of thus far.
