Just killed Krieg few minutes ago and never played TQ before, but I think that this game looks quite promising. I hope I may be able to give some suggestions and help for translation into my language (Korean).
p.s. Where can I find good information about this game? I see GD wikia is not that informative at this moment.

Welcome to the forums!
If you haven’t played TQ before, you might want to pick it up. You can get Titan Quest Gold (TQ and IT) for only $10 on Amazon. It’s well worth the money.
As for helping with translation into Korean, I know the devs released the first set of localization files in that last build and they said they’ll release more in the next build. I’m not sure how to work with those files, mainly because I’m an English speaker, but if you have trouble, I am sure someone else on the board can help get you started. The more languages GD supports the better.
Yeah, the Grim Dawn Wiki is severely lacking. I had planned on updating it, but that is almost a full time job in itself. Hopefully people will add to it over time.
