Lately the games haven't been as interesting as they used to be. I remember being in a 24 player server and the games would last 60 minutes. Mainly because it would end up being a team of 2 vs. one single player. And it wouldn't go directly to deathmatch because it required 2 tributes remaining for the game to go to deathmatch. Me, being the single player a lot of the time, would have to stalk them a bit more and wait for one to make the foolish move of moving into a cave or wandering away from his partner to go get a chest.
Another thing that made the games interesting was when mobs played a big role in how the game played out. Players who weren't well equipped used to have to hide in trees or buildings at night to wait out for the monsters to go away when the sun rose in the morning. Now a days there are hardly any mobs because their spawn rates have been dramatically decreased. I know that the mobs weren't real popular with the majority but I liked having long games. They weren't fun to watch but they were a blast if you where the player, in game, running around, hoping that a creeper doesn't blow you up, or that a player will jump at you.
To me, a lot of the old adventure feel has gone away because of some of these things. When I was new to this when these servers first came out, it was awesome to be in game and to have your heart racing because you just made it into the top 5! That was quite challenging because you would have to fend off mobs and had to be watching your back at every second.
I miss the old days. It's not that I don't like what we have now, it is completely fine with me, but it just isn't as fun as it used to be.
One thing I would change about mcsg is bringing it back to how it was before sg3 was released.
