Would it be possible to make Brink into singleplayer game with huge open world to explore where you do missions, lets take examples like Assassin’s Creed and Mass Effect games and even little inFamous.
Brink was biggest hit on PC, according to the developers, so atleast it would be possible to run it on bigger scale than what consoles could.
The setting is also there. The Ark. There are two factions and the missions could revolve around those two factions, so you would basically have two playtroughs right there. Also the missions in game could be simple errand missions like “Take this paper bag over there and lit it on fire and ring the doorbell” or something like what we have now on the game but just more story driven. This is where Assassin’s Creed comes into play as example, it has open world to exlore and you pick your missions from people around the city.
The part where MassEffects come is is the party. You could get 2, or more, with you and give them simple commands just like in ME, also this would is where your character class comes in play, if you pick heavy trooper you have to have medic along to boost you and hacker to hack and so on.
Now the combat in game would not only happen during missions, there would be random encounters, opposing factions doing their own missions, sort of speaking, and you could stop them or just ignore them but this would affect the games world somehow. Lets say Resistance is attacking Securitys base, if it would be lost in the attack then you would lose spawn point in that area of city BUT you could get it back after period of time and/or if you just fight the forces back.
Options to mod your character could remain the same and you would be rewarded for doing missions and getting better hold of the city or causing more havox in it, depending the side. Also there would be weapon and armor vendors around the city, yes just like in AC games or any other rpg game you see around there.
I know that there are still loop holes on this idea but this is just a idea that I had few minutes ago and just wanted to get it out my mind in here
