You can always find examples for worse software, for spacesims x:rebirth is good one!
But, well, SC presents itself a the reincarnation of AAA-megaquality Space-Game, Tactical Shooter, Fleetcmdr, Privateer, and Blockbuster MoCap Movie.
Just looking at the current state of the game, regardless of it's alpha status and 3-4 year dev, i is still lightyears away from delivering on that promise. The only polished aspect are ship models (i.e. the main source of income). Everything else needs A LOT work. Maybe it will become the übergame it claims to be, but that won't happen in the next 2 years judging by the status quo.
It's early on its stage for certain. But the core of the game, this is, the core features of the gameplay sets on, are there. The Flight, Ship Combat, FPS, EVA, Multi-Crew, getting that core base of essential features is what they needed. Now they have that, they don't have one excuse to be struggling during years on Engine work on the tech that made these possible.
I think addressed that in my edit. "Alpha" is a term that can mean totally different things in different contexts. In this case this is not just a standalone Alpha with testing alone in mind as you suggest. SC´s Alpha, much like Elite´s and other game´s out there, is also geared to help secure and attract further funding for the overall project. Which means it needs to reach certain thresholds for playability and polish.
And it has them, the server may overkill it but i have been there, on performance i actually was expecting worse performance than the one i ended up reaching, and today you can have play sessions that last hours, so this isn't by far the most unstable alpha i ever played, no way, eheh.
Nope. It screams pre-alpha, prototype... something in-between.
And nope, they did not accomplish with their promises. They promised to be perfectionist, to deliver and get out of PTU only when considering release-ready, when passing from the high level of quality of CR, so people "have fun".
They can't use such excuses to justify the delays, taking longer, and then, suddenly change to the "alpha" card, to justify a total broken mess. Sorry, you just can't always move to where the next excuse is. You give a excuse, you stick with that. Then you will keep the trust or any credibility.
Again, their promises for the release of 2.0 on a alpha sage of development, again with the release-ready silliness, release-ready for one alpha playable by everyone.
Feel free to keep your opinion, this release, for me, it's one early Alpha, the core features of the game already have implementations and it's missing a ton of features that will set over those core features, being, that, one Alpha.
And i will not quote the later part of your post to not derail this thread AGAIN to discuss how Bad and Awful CIG is. This thread is about the GAME.
