I will chime in as a backer.(a retard)
Star citizen has only recently become an actual game. But it is making progress. Most of us believe this progress is being totally consumed by squadron 42 instead at the whims of whatever bullshit Chris Roberts feels like implementing these days. I love playing star citizen when it wants to cooperate and play nice and I absolutely despise it when it has as much stability as Terry Davis. The biggest issues are server performance and player sync at the moment.
Performancewise star citizen has had huge gains in graphical performance over the past year and it went from unplayable on my 5+ year old system to 30-40fps at most points
at sub 20 players the servers run stellar however once they pass this it starts to bog down severely, but even at 110 players it doesn't become unplayable.
Server size has increased from 50 to 110 within the last few months as they continue to stress test, and they are talking about upping it to 200, I imagine a lot of the performance issues are caused by the game likely running in debug mode at all times.
Other developments of note include how squadron 42 has been removed from the store page for a few months now ahead of citizencon with no word on when it will be returning, however a recent monthly update on squadron 42 stated that the "level design teams have finished the majority of their work and have moved on to quality assurance" (ie; making sure there arent random soda cans and plants floating around)
Another large development is when starfield released star citizen suddenly had a large array of quality of life improvements announced for then next update coming this year almost overnight. This tells me that Todd Howard has definitely shaken them considering their position was previously not bothering with QoL and major bugfixes unless absolutely necessary.
My current verdict as a backerfaggot is to simply wait and see if they actually cough up anything on SQ42
If you are going to actually try the game then I beg you to wait for a free week which happens regularly enough instead of actually buying in.
If you are interested in what the game looks and plays like try watching Buzzcut hes a planetside 2 vet(number one on the leaderboard for terran republic) and has a pretty middle of the road opinion on the game
Also for the love of god I hope they implement FSR2.
