While Solasta does look good you have to remember that they are not operating using the full Players Handbook they are using the Open Gaming License so unless that changes classes like the Warlock and races like Tieflings aren't happening and so far they have no plans to make it multiplayer or allowing multiclassing. If your ok with that going in thats great, after all it still looks like a decent game but don't expect those things to become available or complain when they aren't part of the game, now that being said they have commented that when Modding starts happening anything is possible but of course you are using those at your own risk per say
Sidenote, but both Tieflings and Warlocks are in under the OGL.
