Having played the game, got all endings and all achievements in the game, I can that this was a very fun, challenging, and refreshing experience.

While the game can be challenging for some of the uninitiated, if you put in time to understand the mechanics of the game (the shop, the various parts, OS tunning and stats) and the tools it provides, it can be a rewarding experience. But aside from this, I recommend taking your time with the game and enjoying it. YOU DON'T NEED TO BEAT IT IMMEDIATELY (but if you want to, have at it!).

The story was very interesting as from NG to NG+ you are faced with choices that affect a world and forms of intelligent life both options ending with the idea that there could be another way to approach the overarching core issue. It was compelling seeing each character motivation and them revealing what their ultimate goals were but it did leave me wanted more out of the characters, lore and some of the missions (i.e. More banter between character and maybe some more data logs); but that's my wanting. If you play it you might have something you find wanting and something that is amazing here.

Overall, I highly recommend the game. I had a lot of fun and it gave me a bit of a challenge to overcome. Please keep in mind, I recommend this not because it's "challenging" or "hard" but because I enjoy my time playing this game.
