I have yet to play Torchlight 2 (it’s installed), but the first one was awesome, really great, simple, straight out fun, and it looks like the second is just bigger and better.
So, on topic, D3 has a more impactful combat, it feels “heavier” and better, I am a lover of musou games (Dynasty/Samurai Warriors), and D3 to me feels like an extension of that, endlessly mowing down demons (enemies) just like I can do on musou games, but with a deeper customization to skills and ways to keep doing that.
On the other hand, while the combat also feels really great on GD, my focus on this game is building my character. I spend more time than I should just thinking on what skills to use, when, how to get there, and trying to keep the build up to date with any new and improved gear that I may get.
I am still a rookie really, about 16 hours only of GD gameplay so far, so I don’t know this game enough to compare more advanced stuff… it’s just incredible, and I felt at home having played Titan Quest.
When Season 12 starts on D3 I’ll play that again, some great changes are coming, and untill then and after that, Grim Dawn it is. A kind person gifted me the Ashes xpac so I’m really happy and looking forward to play more and more.
Do try PoE when you can, it’s not a bad game, I just didn’t find things that I look forward to in an ARPG. Also, it’s free.
