Topic: Petpetuum will be amazing... in 2-5 years.
I might be wrong on all counts, but as a newbie trying the 15 day trial, that's how I feel.
In short, the game has all its bases covered as a bare-bones system for a truly phenomenal game. That bears repeating: it will eventually be a phenomenal game. Right now Perpetuum is SO bare-bones it seems to have little to drive players to actually play.
I feel addressing these problems would go a long way:
No story in a clearly interesting game world
The world looks amazing. There is so much potential depth there just looking at the interesting structures. There is a great backstory that anyone can read on this site. It's a shame there is no lore, no storyline in the game itself. It was one of the strong points of the original Mech-type games and kept me playing them for a long time.
The game is getting LESS friendly to new players
They took out the 10 training missions. I understand perhaps consolidating them a bit so it goes faster, or let people do several in parallel to speed it up. But they are just gone now. No way to get your Mk.2 Ankhe. No way to get into a better light robot after the initial 10 missions.
Speaking of speeding it up
People seem to turn to transport missions to make their fortune. It seems to be universally agreed upon that they are mind-numbingly boring, but safe. Additionally, the combat missions are slightly more fun, but they have more travel time than anything. They end up being just like transport missions but with a higher risk of losing your bot. Long, boring travel times is a bad idea, especially in conjunction with:
The grind starts immediately (and lasts forever?)
You have to grind out the same assignments (literally the same) if you want to get a rep up. It doesn't matter much anyway, as the other assignments are the same thing, with the details slightly different (different location, slightly different bots to kill, etc.) I hear joining a Corp and running around doing things is more fun, but I also hear that doesn't really address most of the fundamental problems of the game.
TL;DR
The game has a ton of potential. Right now it is riddled with problems: No storyline, no incentive to play beyond the first couple weeks of wow-factor, not newbie friendly, the game is just one big grind.
If they put in a storyline, figured out how to make the game feel less of a grind, added in better long-range transport, added in newbie-friendly support, and threw in all sorts of fun incentives to play long term - and then advertised it well - the game would kick some serious bootay. I look forward to checking back in on it in a couple years, for sure.
