Civ 5 sure takes a lot of your day

It's like you start playing, then 300 turns later you check the time and go "oh christ!". I'm really enjoying it though. Some of the leaders are really fun, while some can be frustrating if you get the wrong map. For example Iroqoi have an advantge being near tons of Forest tiles, and if you are playing on the Island-type map you lose a LOT of that advantage because there are very limited forest tiles. While leaders with naval advantages dominate.
 
I started my first Epic-length game on difficulty 5, and 350 turns in I realized that I'm way behind because I don't have access to the correct resources. So I may just abandon that one, though I THOUGHT I was playing pretty well. Then Washington and Ottomans decided to both attack me at the same time.
 
Multiplayer could use some sort of save function, because even a Quick-paced game is 3 hours. My friend told me there might be some sort of auto-save function in multi, but I don't know how helpful that is when trying to just continue a multiplayer game you and your friend were playing.
 
I'll definitely have to play it here and there and try to get better, but I think I'm finally coming off of the binge playing of that game. It is such a blast though.
