Get off your high horses and smell the air. Jesus. It is beyond me how some people find movement or combat to be lacking. Compared to your belowed DA:O, combat and movement is leaps and bounds better. Close to all the mechanics of DA:O felt forced, tiresome and borderline annoying. The inventory was, admittedly, well put together, but very few things besides that actually worked well. The RPG-elemtents were undoubtedly top notch, but the gameplay was at times painful - at least to me.
It's easy to forget though, 'cause as with a lot of other things, memory is a ******. Our brains tend to keep the good parts closer, and put that bad things further behind.
To me, it seems a large group of people forget a major component as to why DA:O is looked to with such high regard: it was the first Dragon Age. I've played NWN and BG, but when DA:O came out, it was something new and brought new things to the table. It's the same thing with World of Warcraft. More or less EVERY MMORPG made after WoW are superior games in terms of mechanics, interface and even storylines. However, it took other developers too long to put out their games, and by time the time they came out, it wasn't new anymore. If Dragon Age: Inquisition was the first Dragon Age game in the franchise, I'm pretty sure most of todays critics would wet themselves with excitement throughout the entirety of the game.
