I have been thinking about running an online game for some friends I meet playing other games online.
They have a good group of Pathfinder players and I told them I had every edition of D&D ever printed along with Pathfinder and various clones such as Castles and Crusades and ACKs.
In recent years we have been playing 5E and AD&D/clones. I have not run a 3.x game since 2012 and have not played Pathfinder at all since 2014. One of the guys wanted to play a Shadow Sorcerer no idea what that was but I can take a few guesses. My idea of a shadow mage is in 2E Spells and Magic book from 1996. The last PDF I bought was Ultimate Campaign and the last AP I paid attention to was Skull and Shackles.
In 2012 I was burnt out on 3.x games as I was an early adopter of 3.0.
Some of the players have played other editions of D&D/3.x but looks like Pathfinder is the only one everyone knows how to play. ANyway I am thinking about running a game of Pathfinder but core rules only + ultimate magic/comabt being allowed. I might allow class from another book but spells and feats would still be limited to core rules+UM+UC. The main reaosn is I actually own those books on hard copy and do not mind looking up the PRD for an online game.
I also asked them if they were fine if we did not use magic item shops. Magic items will only be what you can find and maybe trade for WBL guidelines well not be used. The PCs are likely to be over equipped in terms of $$$ but they will not have the choice to marry up the perfect magic item with whatever feats/class they have chosen. For example someone might chose a very suboptimal fighitng style like dual wielding weapon finesse daggers but they might have a +3 or +5 dagger which RAW breaks the WBL guidelines but they can't sell that dagger and then buy exactly what they want.
