I love Dragon Age: Origins. One of the best “modern” RPGs for sure. Great replayability. Great characters. Great “rpgness”.
I also love Dragon Age 2. It’s not a great game… but I actually like the story more. I like how more “focused” it feels narrative-wise. The characters are also great. The “rpgness” is less good… and development issues makes for a lot of reused assets.
I kinda like Dragon Age: Inquisition. I’ve been replaying it recently. The story is decent. The characters are also good. Maybe even better tbh. I like the main plot points and the ideas etc. But the game mechanics kinda suck… I hate the pointless missions that take time like mobile games. The way the story progresses, with meta-points blocking things also sucks. But it’s ok…
All in all, I would recommend playing them all. But kinda like watching all the Godfather movies. One is great, another is pretty good, and one kinda sucks but it’s ok. But if you just watch the one that’s great, you kinda miss the whole thing.
