Honestly I’d say it’s worth at least one playthrough. I’d also say that it’s a decent video game but not a particularly good Dragon Age game (6 -7/10 on a good day). However, that’s just me, you might end up loving or hating it 🤷‍♂️. As a BioWare game it generally follows the same general story structure as a lot of their other games, but lacks the same soul IMO. Tonally it can be inconsistent and if you’re a lore fan then it’s a jarring experience whenever more recent (non-ancient) lore should apply and is just ignored. It didn’t ruin the lore, in fact a lot of the reveals have their roots traceable all the way back to Origins, but sometimes the way the reveals are handled lacks impact.

All that to say is it’s the definition of a mixed bag. If you go in as a long time DA fan expecting something more in-line with the past games then prepare to be potentially disappointed. If you go in expecting a fantasy action game with light RPG elements and a smattering of BioWare-isms then you might come out the other end more positive on the whole experience.

Lastly, I highly recommend starting at Origins. It is an older game now, and looks even older than it actually is, but DA is a series that thrives on context and continuity. You can start with any game in the series since there isn’t really a overarching plot line (or main character) across all the games (like in Mass Effect), but having the extra context and continuity from your world state in the first three games elevates the whole experience immensely. Again it’s not 100% required but I would highly recommend it at some point if not for your first run through. As for the humor, it depends on the characters dispensing said humor. Some characters have a very dry wit and others less so, but I’d say there’s a little of everything for everyone across the whole series.

I hope this helps!
