Off topic I know, but Valkyria Chronicles made me cry so baaad. Specially at that part of the game when one of the main characters meets a terrible fate. The voice acting in English and Japanese both nailed that scene well.
What is even worse is the decision to make Valkyria Chronicles 2 and 3 on PSP only. Whoever made that decision should be fired...immediately The again, it is Sega we are talking about so I am not really surprised. I guess Valkyria Chronicles 2 didn't sell as well as was hoped for (gee big surprise there), so Valkyria Chronicles 3 was exclusively made available in Japan. To get an English version of Valkyria Chronicles 3, you have to rely on an unoffical fan translation.
But on Topic: OP, if DAI is the best RPG you have ever played then you need to play more RPG's. I am guessing you are just saying that to counter the negativity you see on the forums regarding DAI. This is similar to people posting 0 score reviews or 10 score reviews on Metacritic to counter what they perceive to be unjust / unfair criticism on way or the other. This is also why I tend to avoid Metacritic or, at best, take Metacritic scores with a grain of salt. Some of the DAI criticism is entirely justified (example: Poor Keyboard and Mouse controls on PC, poor tactical combat / lack of tactics in general, and yes even lack of customization option - read: hairstyles especially for qunari and females in general ) while some criticism is at least somewhat questionable (example: No healing magic, Not enough love interests, No Dorian romance for females / No Sera romance for males, etc.).
I have played many traditional RPGs (and hybrids to include action, tactical and even fps / shooters) and would consider the following among the best I have played: KOTOR1 and KOTOR2 (despite content being cut due to cost / time constraints), ME1, ME2 and ME3 (despite original ending and initial multiplayer requirement to get best ending controversies), Jade Empire, Valkyrie Chronicles, Shin Megami Tensei / Persona (series), Dragon Age: Origins, Fallout 3, Elder Scrolls: Morrowind, KOA: Reckoning, Xenogears / Xenosaga (series), Grandia II (Dreamcast version), Borderlands 2 (Xbox 360 including all DLC) Diablo III Ultimate Evil Edition (PS3), XCom Enemy Within (XBox 360) and the original X-Com: UFO Defense (for PC back in the 1994 - courtesy of Microprose RIP), Lunar and Lunar 2 (Sega CD - courtesy of Working Designs RIP), Chrono Trigger, Monster Hunter 4, Final Fantasy (some of them). There are probably others that I could include as well.
But if you are actually being serious about DAI being the best RPG you have ever played, then more power to you and to each his own I suppose...
