I've never played a game that tickles the incessant need to innovate and streamline quite like Satisfactory does. Starting fresh and building up to an automated empire from just a HUB and a dream is unlike anything I've ever played before. The fact that it has multiplayer (despite the bugs that can and will be eventually patched out) just sells it even more for me.

PROS:
- Giant map space that allows you to choose anywhere to build and start your bases and factories
- Satisfying risk/reward for progression through different tiers of unlocks
- Streamlining production is a reward in and of itself, allowing you more time to automate other processes or to explore the world
- Option to play with friends that own the game on EGS/Steam or just Steam itself
- Death isn't necessarily a detriment; dying places your inventory in a small storage box that can be recovered
- Physics are fun and wonky, allowing for you to air strafe as you jump from conveyor to conveyor through your factories
- Every resource is necessary, as small/insignificant as they may seem (aside from a few WIP resources in the game's current state)
- World accessibility is linear with HUB upgrades, meaning that some areas are "inaccessible" until the proper upgrade is completed
- i.e. certain areas are poisonous, but can be traversed by liberal use of food items to stay healthy OR by wearing proper gear to negate damage entirely

CONS:
- Absolute time sink, nearly 140 hours of gameplay on my main run and I'm only at Tier 7 of 8
- Crucial resources can end up being a far ways away from your base, meaning you either have to bring it closer to you or build facilities out closer to them
- Multiplayer is a buggy mess in the game's current state, so buyers beware (as of 0.3.5.3)
- De-sync causes problems with non-host players
- Game updates happening later than expected with regards to player position and destructible terrain
- Using vehicles (vehicles rubberband/teleport around or vanish completely after killing the player driving them)
- Players joining a session that's had a long up-time can potentially cause game crashes due to some index out of bounds error
- Choosing the online connectivity is a one-and-done process; changing your decision requires account service help

All in all, it's a great game. It may have some bugs and performance issues in its current state, but for a sub-5GB game it has DAYS of content. Cannot wait to see what the devs have in store for later updates.

Edit as of Steam Award Nominations: the devs pushed out a fluid update and finally introduced ladders, so the game has content updates even 5-6 months after release. Future of the game looks good.
