Some points I'd really like to see in DA4:
- more complex side quests (more quality/less quantity)
- good and evil choices with real consequences
- less collective quests
- day/night rhythm und different weather
- cinematic view in each conversation
- a PC with more personality (I miss sarcastic hawk)
- some really nice background story für the PC (I want to feel as special as I felt when playing as Revan in Star Wars Kotor) or give us the origins stories back
- the same quality of companion quests as in DA2
- a longer main story
- a good plot twist
- a story that takes place in Tevinter
- a less static world (In DAI, you get to know most things about Thedas through codex entries. I'd like to see more NPC's in the world who actually talk to you.)
- Please don't let the game look like a construction kit. In DAI, each area was created in a similar manner. (astrariums, shard hunting, mosaic pieces, collecting plants and herbs, collecting materials for requisitions, giving object x to person y, etc.)
- give the same amount of romance option for straight male/female, gay und lesbian people (or at least not always more romance options for the same group)
- please make the story relevant romances bisexual, so that everyone can experience them
- give lesbian and gay people an ice king/ice queen or a knight in shiny amour
- give straight males a romance option that's NOT human again
- make Harding a bisexual romance option
- give at least one romance option to straight male/female, gay and lesbian people that looks beautiful ( I know it's a matter of taste, but just compare Cullen and Iron Bull. I like both of them, but I think it's good if everyone has at least one traditional beauty to choose from.)
- please make the first meeting scene with the companions more special (no simple "Hey, I want to be in your team, okay?" anymore.)
- give us better hairtslyes and beards
- I'd like to see longer hair for females AND males, too
- More casual outfits would be nice (or at least better looking ones)
- More puzzles and riddles
- bring the brothel back
- give us caves back
- give us attribution points back
- give us more specialisations
- create the world a bit darker, more scandalous, less Disney like
- don't orientate too much on Skyrim. Dragon Age should keep its own charme
- it would be nice to have a place as in the ME Citadel DLC, where you can do private things apart from the actual adventure (maybe some mini games)
- please concentrate on single player mode
