I think you may be taking this a bit out of context. Grava has over 800 hours in Grim Dawn from various playtesting sessions and working on the game. He is not a hardcore ARPG player though and does not study the mechanics as in-depth as many players here.
I myself have well over 1500 (and that’s only counting the hours after Grim Dawn was first put on Steam).
What we do not do is go out of our way to play Grim Dawn in our off hours. If all we played is Grim Dawn, we would never have an opportunity to absorb other games and thus draw inspiration and lessons from them.
Except it was:
I appreciate that you prefer my streams, but we don’t do these streams to exclusively spoil new info. And not everybody watching has necessarily seen previous streams.
Last time I streamed, I barely progressed into Ultimate at level 1, whereas Grava went considerably further.
