Too many stuff i want to happen/change and at least 90% of them won't but still...
1) I hope they'll move timeline somewhere away. Sticking to same or close timeline can cripple the series. Though it'd be great to see videos, news or some info about Shephard.
2) I hope to see some kind of nice and detailed space combat with upgrades that have pros and cons, with seperate skill sets etc. Might even order our pilot and crew to concentrate fire, pull back, give "all non critical power to shields" etc stuff.
We could take control of the ship or get in a turret or view the "battlefield" on tactical view whatever. We could board to other ships aswell. Would work both SP and MP. (Not in upcoming game but next or maybe even later)
Maybe our guy/gal can be pilot him/herself. So we can pew-pew stuff with our interceptor. What good is ship if there's no space combat anyway? Basically space truck, bleh!
3) As gameplay i want a total support class, like Combat Medic. Buff(Obvious), debuff stuff(Poison clouds, acid bombs) instead of pew-pew, use power rinse and repeat.
4) I heard about Mako's return but i'd also like having a few more vehicles. Hammerhead could be nice but even then that's not enough. Maybe something like a zodiak boat? Or even planetary flight. With all their pros and cons aswell. If we gonna free roam(kinda) let us use the vehicle we prefer.
5) It will (Probably? Surely?) be open world. But they should do it in New Vegas style, not typical Korean MMO stuff. If i kill someone he/she should stay dead until their reinforcements coming, not magically reappear in a few minutes to haunt my life. Walking dead <.<
6) Should be tested with proper controls(aka keyboard+mouse) for PC. Having a PS4(And had PS1-3 aswell) I hate to use joypad on PC as principle. (Aside console gaming i also have a joystick for flight stuff and a G27 for driving but using joypad on PC makes me feel like 2nd class citizen)
7) Simon Templeman for main male character voice. Too bad we probably won't have Jennifer Hale as female player character VA, love her always and got used to her.
8) No fetch quests. Call it mineral scanning or "Get x of y's" i don't mind. Not only i hate it, they don't make any sense.
Instead we should be able to make a deal with resource suppliers, maybe ask from our "sponsors"(Alliance, council, Cerberus whatever)
It always made me sad that they have nearly "unlimited supplies" and Shep was "last hope of humanity" and "on a really important mission", "has their full support" but need to do such non-sense stuff.
Instead let me do quests for some mining company, let me invest in some mining company, let me raid some mining ship, let me at least buy them via credits. Something else.
