Bit of awkward phrasing, but the commentator was not talking about Steam exclusivity - rather having it available on Steam (in addition to wherever else it was available).
Clearer wording may be “if only it had been on Steam”.
I wish I was still connected with those I played NWN with. Bastions of War, an arena PvP server, let to same great squad play - and from there we expanded to other servers under the moniker “Cult of Discord” or CoD.
Why all the detail? Wishful thinking that when one of the other post members decides to search for Cult of Discord (as I occasionally do) that they turn up a result.
I was an on and off reader of theirs and really liked it in the beginning… but had the distinct impression they changed ownership a little while back when they added some pay walls and game guides.
