So I'm currently doing a group project in class, and my group had chosen the question of "how do video games affect your heart rate". One of the 4 games we had decided on would be Civ4. We can only play for 15 minutes each, so I was wondering what would be the best map type/mod/settings we should play on? It should be so that when 15 minutes is over, we have at least reached the Medieval Era and/or have died. Oh, and my friends have never played Civ4 before. So basically, I have to make it to the medieval era in 15 minutes and my friends can lose in 15 minutes. Currently, we're doing an 18 Civ Duel Pangaea on Monarch. Is there anything better?
