Same here. I've played Ps:T, and I found it to be highly overrated and not very interesting or appealing.
That's a shame. I played it for the first time maybe a decade ago and I freaking loved every minute of it. It's one of my top 5 games of all time, no joke.
It is a shame. Especially with kanisatha preference for not doing combat, I expected Planescape to be his THE RPG.
It is, because I played it for the first time only recently, after the EE was released, and went in with all those built-up expectations of people telling me for years what a great game it was. but I found it just so-so and not anything great. I think it just comes back to my low evaluations of Avellone's writing. As for the combat, technically, my preference is not for no combat so much as it is for melee combat over spellcasting (though I'd be fine with no combat).

I enjoyed games Avalonne has worked on. I can't say what imput is his or not, but he does seem to be a positive presence. He can be wordy, yes, but I feel he understands medium of games very well - his characters tend to be well inwined with campaigns, and reference players actions in interesting and organic way. He knows what players will be doing, and he writes for that, which I think is a rare thing.
I must ask: Did you try recent Disco Elysium?
