Help with restricting splatbooks
Hello folks!
So, my friends want to try 3.5e (they played only 4e and 5e/5.5e when D&D is concerned) and i've decided to DM a simple sandbox for them as soon as i've finished our current campaign arc.
My idea is to make a simple mini-setting, something like 12~15 hexes with a bunch of interest points, a few dungeons, rumours and dangerous monsters to hunt in the wild, pretty simple sandbox emergent gameplay stuff. My inspiration would be the Dalelands of Forgotten Realms (Mistledale, maybe).
That being said, i'm torn about which splatbooks to allow in this. I don't want to go "PHB" only, but i also dont want to open the floodgates all at once. I'm a long time DM, but it's been a LOT of years since i've run 3.5e, so my knowledge about the diverse splatbooks is rusty.
My idea was PHB + Tome of Battle and maybe one more splatbook. What do you guys think? Any recommendations?
