Final Fantasy, For its thematically rich stories, Consistently different game design and ability to genuinely surprise me at how good a game can actually be. It got me into 'proper' gaming (i.e 'hardcore' games) and if it wasn't for this series I wouldn't still be gaming today - hands down. In a time when a lot of games (not just RPG's) seem to be clones of their cousins' from the same company FF is constantly switching itself up and of late each iteration has become more and more progressive & boundary pushing than the last (to the anger of many westerners and the proud crowing of my Japanese friends).
On a side note the Atelier series gets an honourable mention though not being an option for also being on the improve and being so quirky in concept and execution. For a series with a low budget it has proved markedly survivable, produced some of the best characters around and is by far my next favourite series next to Final Fantasy. In my personal opinion (and I know no one will share this, but no one here plays atelier games anyway) they have long since perfected what bioware has always tried to achieve re:choice, multiple endings, multiple plots, different npc's with their own side quests & back stories etc etc etc
Cant go without saying this too, last honourable mention Nier, for Grimiore Wiess, a character more perfectly Byronic than Byron himself and the ability to see the main quest from the enemies perspective after first playthrough (and how horribly sad a game can be)
