As I don't play a lot of games I'm basing my top 3 on my favorite games both on console and PC over the last 10 years.
1) Larian goes to first place because not only do they make good games they listen to game fans and care about their games not just making them just for profit. There are a lot of mediocre games out there that are very popular due to big publisher's might (EA cough, cough) and smaller devs / publishers that make genuinely great games miss out.
2) The now defunct Surreal Software for making the Drakan series of games. They were similar to Larian and were involved in the community until they got bought out then later shut down.
3) Hard to say. I like the Witcher games so I'd have to say CD Project RED but Infinity Ward would be a close second for third place (fourth?!) as I always enjoyed the short but sweet COD games.
