I think the game that needs the biggest update is DA2 and while there are somethings that can't be fixed in a remaster (the story is going to be just as frustrating as before) what can be altered to make playing the game more fun? Well, personally, reducing the number of enemies you have to fight would be a MASSIVE improvement. One of the things that bugs me about DA2 is just the fact that you have to go up against no less then THREE Waves of enemies and because most of the gameplay is combat based this got very tedious VERY quickly.
So, I would like the game to just have One Wave of enemies, reduce the number of fights so you can go more then 1 foot without getting into a fight and simply double the amount of XP you get during those you do fight. Second, Include a Let Anders Down Politely. I may not like Anders but having your only opinions be romance him or be rude to him to just be a massive 'What?' in the game.
Second, have getting Friendship or Rivalry points easier. MELE is changing up the Paragon and Renegade System so you can get certain dialogue options that were originally only acquired by going full Paragon or full Renegade and that was VERY annoying. In my most recent play through I tried playing the game in more of a middle of the road Shepard and I did this to get the Shortest Interrogation of All Time bit in ME2 and despite getting Renegade half way up the option was STILL locked off to me because I wasn't renegade enough. Thing of it is I don't Like going full Renegade.
I like being a nice person who helps my friends and being there when they need me. So, I'm glad that BioWare is changing that up as I honestly do think the Light vs Dark Side system just hasn't stood the test of time and the Friendship/Rivalry system was frustrating to work with because to get certain story beats (like Isabella staying) means that I can't play the game how I would like to. Dragon Age Inquisition managed to fix this by having it were if you didn't bring a certain companion with you would still get their dis/approval for doing something they would or wouldn't like which included big story moments.
Another fix is to just give players the options of giving a few High Level Gifts that are good or bad to gain the amount of friendship/rivalry needed so you don't have to bring a certain character with you to get the number you need or at least get them started so you don't have to bring them along as much.
And finally, give us the option of being able to play as a Mage, Rogue or Warrior and keep which ever sibling you want alive. Bethany is much more likable then Carver but Carver does improve if he joins the wardens.
Just give players the option at the start of the game who will live and who will die simply by assigning one of your kid siblings to protect mom and THAT'S what determines who lives or dies.
And in regards to Origins, eh. It's fine as it is mostly I would just want some more updated graphics and maybe a better looking combat animations and have the mana system more like it was in DAI but that's about it.
And that's what I'd like to see in a Dragon Age Remaster Edition, what about you?
