I really don't know, it's up to you...
I also could say I never played DnD games, or maybe I did, but I don't remember, so there's that.
But I know what I will do: will play starting with early access, just for the graphics and to listen the talks; role play could be fun a while, and maybe set up an ambush (or rather fall into one, and in that case I'm so ready to dodge out, except there are no dodging buttons here)
Why I still buy it? I just liked that presentation vid. Some say there will be "chicks" as well (though sex with aliens doesn't excite me), and maybe won't be any. Sooner or later will be a "god mode" cheat, so I can go through and enjoy the story without being stuck in these fights decided by dice or rules I never knew. Because in these games you need a proper counter to pass through, can't just hack and smash.
I'm really prepared to play a bit and then get stuck, then will play something else until there are mods to help me through. I never ask for refunds and I will like the game no matter what, just because helps me thinking. There are all sorts of games and people can have fun doing these "table top" activities (whatever they are, never saw anyone playing these). That's good. And I support good, sometimes.
Really want the smart parts from this genre to get into MMO and other RPG games, because most of those are so mindless "press the skip button", one way or the highway kind of stories.
If this will get tedious, I will just stop playing. Mods and save game editors will save me in time, then I can see the ending, because some parts are just painful if you don't enjoy this kind of "challenge". And if it's not fun, what's the point playing a game? But still, until that point, will be fun: character creation, starting vids, on to that first trouble, maybe even the second. I don't expect more, and thus I'm sure I won't be disappointed.
