Just finished watching the 6th episodes, watching dual screen and enjoying it a lot.
My few suggestions:
-As n9103 suggested the time display would be great, I noticed you said it doesn't work in multiplayer but with a little convincing I feel like the mod maker would try and help you guys out.
-Without the time mod it would be nice for you two to actually coordinate your recordings.. 3, 2, 1, start recording, end recording, go live, etc.. It's a bit of a challenge to sync up your two feeds right now, I basically just hope that you talk at the start of the game and if not I scroll through until the first attack and do some math back to the beginning. Not to mention the video lengths were quite off so I was watching episode 2 of one and 3 of the other and they were matched.
--Watching Fish rob Xterm in real time was quite funny though
-I know this series has started but a couple ideas to make future ones run much smoother
--Custom make your PvP map (build enough resources for both players and within reasonable distance away)
---You could even play around with a map where oil is only in the middle of both of you two, or water, have enemy "rebel" aliens guarding certain premium resource patches etc
-Turn up the speed of the game
--This is PvP it shouldn't take an hour (or two) to reach green science, up the speed and it will become who can build a better base and has better tactics
---Granted this was probably kept low to work better as a series for YouTube
-Have an end goal (I don't know what it is for you guys)
--Once you die the other person wins
---Unlimited deaths but you have to blow up the other persons "Capital" structure (mod in a building that can only be placed and not picked up, one for each person at the start or placed already in a custom map)
There was a lot more ideas I had while watching but those are just what I can remember right now.
Anyways, Keep it up and keep the videos coming! I think with this series as a proof of concept I can see a bright future for people expanding on this idea greatly.
Cheers!
