I recently ran my group through Temple of 1000 swords and had a blast! I made a few changes (mostly just the name of Gladio -> Fulad-zereh/Fulazarus). The group managed to get the Nine of Swords and lost their fighter. Poor Tiffany asked of Fulazarus to make her into the ultimate warrior (she felt a bit incomplete after having lost her right arm and her ear earlier in the campaign). He told her to jump into his forge. She emerged as a horrific humanoid abomination made of swords and the rest of the group later decided to put down this mockery of God's creation. Rather morbid, but hey, more loot for the rest of them!

As is the inescapable of all who play OSR games, I have begun cobbling together the framework for my own system. However, I feel I lack the experience to truly make it great by myself and wanted to look at some other people’s systems for ideas and inspiration. As such, I’m looking for OSR rpg systems that have the following features (listed in order of importance from high to low):

1. Four base ability scores.
2. A class based character system.
3. d20 resolution mechanics.
4. XP-based level progression via treasure and combat.
5. Rough compatibility with B/X modules, or at least requiring only marginal effort to adapt them
