I loved Jade Empire. Of course, that was a Day 1 buy for me, back in the days when I actually did buy some PC games upon day of release. I really loved the atmosphere, characters, settings, and lore. I could see combat aging - but like most BioWare games, it's your best bet to play their games closer to release b/c of how different, odd, quirky, and/or not-as-good as other games combat in their games often are.
As fro DA2 and ME: Andromeda - both were panned hard b/c they aren't that much like their excellent previous games and both of those had to follow-up masterpieces. So, those games never had a chance, TBH. While I do thing they both are decent at least, their previous titles were amazing.
DA series.
DAO was amazing old-school style CRPG; and DA2 tried to make it more action-y and experimented w/ having multiple Chapters w/ different story arcs entirely. But, DA2's biggest issues were recycling environments, dumbing down strategic element, removing tac-cam and weakening character customization (for equipment).
ME series.
ME1,2,3 are all great games - where each one got a bit more action-y each time around, but that made sense b/c it played like a shooter control-wise. But, those 3 kept the hallmark choices, characters, and story-excellence BioWare's known for.
ME: Andromeda might've improved combat immensely w/ movement, direction, and whatnot (jump jets let you zip up, down, and around; dodge move makes you go often sideways, even though could depends on which one you use; and enemies can destroy some covers to get you moving out of cover or lob skills/grenades at you to get you moving). But, the storytelling, writing, characters all felt under-developed and bare-bones; not a ton of choices per quest; and most of the game felt like UbiSoft open-world syndrome with collect-a-thons, one-off quests/fetch-quests/MMO-type (Kill X guys, go to X area, find X things, do thing X times)/fetch quests everywhere - that eventually, even if you like the game...there's a point where you could say "Is this game going to stop being repetitive and/or going to end its story?" It's basically the Mafia 3 and UbiSoft open-world game problem.
