Dragon Age 2 got a chilly reception at launch but has aged well considering what came after and is definitely worth a playthrough, doubly so with mods
(DA2 I completed thrice to really explore the wild variety of the story tapestry coming out of DAO, which also lent a lot of interesting feeling to how well developed DA2 was but it wasn't always obvious in a single playthrough. and I don't expect to have that many finished playthroughs of any of the others. I think that's why it ended up my favorite.)
it had many issues, but the writing was still great, the story compelling, and the characters human. so people were disappointed that it didn't match or exceed DA1, but it was still a good game because of the writing, and people grew to appreciate it.
