The VOIDRUNNER'S CODEX is LIVE! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
I like D&D, Saga Edition, and Book of Nine Swords, so it stands to reason I will like 4e.
I like the idea of every class having a mix of per day, per encounter, and at will abilities. It sounds like it keeps in resource management and attrition without over-encouraging a short adventuring day.
If anything, it would be monster stat block simplification, and XP reward simplification. Being able to do more "on the fly" with a by-the-book logistic to act as a guide instead of winging it myself is a big plus in my book.
Seeing how a fantasy RPG with traditionally quite simulationist action-resoultion mechanics handles the mix of at-will, per-encounter and per-day abilities for all classes.
Also seeing how the game handles divergent build rules for PCs and NPCs, given that same traditionally simulationist outlook.
