I'm in a server of 3 people, including myself, both of the other players are a million times more experienced than I am. Not too much to "show off' there
I enjoy the flight of the MPS, but that's because it seems to go forward with a lot of speed, while the Nano chestpiece is very slow. So, to me, it is better. Now, I may be controlling it wrong, and the flight for the Gravichest may be different, I'll have to try it out when I get it. I tried it in creative, but couldn't get it to work. I pressed "F" and it said it turned on my gravitational squirrel launcher, I'm paraphrasing, as I do not recall the exact sentence.
One other thing I'm worried about is power. With my MPS, I never run out of power. Never even get close. But, just a simple flight from my base to my quarry, about 2k blocks, used up a lot of power with my nano.
The main reason I wanted to use the nano/gravi is the advanced diamond drill is beautiful with its speed, not to mention it can be enhanced, while the power glove cannot. But, by itself, it is INSANELY quick to run out of power. So, the Gravisuit seemed like a nice way to go, unless I just wanted to run around with lappaks in my bags all day.. :U
Edit: Also, if DRPG is so.. alone, is there anything you can suggest similar to it? I LOVE exploring the Minecraft world, and that seems to have so much to do and explore.
