If Bioware doesn't repeat the mistakes they made with DA:I, it might be an interesting game. The thing they must do is kill all the stupid fedex quests that don't even try to pretend they aren't fedex quests. After the 100th quest that's simply "collect 200 items of this kind for 50 gold" I put that game aside and probably won't ever return to it, even though the main plot is somewhat interesting.
So... I realize such quests are sometimes inevitable, but please, camouflage it a bit. Add a story to a even a simple side quest. Make me want to collect something for someone. Take a look at The Witcher 3 and learn
I hope they keep the high dynamic range audio EA likes to use since Battlefield. Probably the only thing I remember from Mass Effect 3 were the sounds. Explosions were loud as hell, traveling though the relay made my neighbors look out their windows... and if anyone would like to have lower dynamic range to play during the night or something, there was an option to change it. I hate it when some games have poor dynamic range, where the weapons or explosions or anything that's supposed to be loud... well, isn't. Like grenades exploding in the new Doom, that's just wrong
Anyhow, I really enjoyed Mass Effect, the first one being the absolute best. The story was fascinating, kind of had a Battlestar Galactica feeling to it, but that might be because I watched it at pretty much the same time frame. It did kind of go sideways in the sequels and each one of them got further away from being an ARPG of any kind. I'm not expecting dice rolls here, but give me some meaningful character stats I can upgrade during level up that aren't a skill tree.
