Pretty much, not many people really like to participate on early access games. Some can't deal with constant bugs, crashes, wipes, and of course the worry that you might burn out early on and end up hating the game. I've seen quite a lot of people during the early Elite testing ending up burning themselves out and had to take huge breaks.
Also, when it comes to Star Citizen a lot of people are also put off by the way the alpha testing is done. CIG has basically put everything behind pay walls. You want those shields? You have to pay real money...oo shiny weapons...give us $15-20....ohhh I need better ship to stay competitive....drop $100+....No other game, early access or not has managed to monatize the development as much as CIG. For the past 8 months, you cannot earn UEC to purchase items, you have to drop real cash on it. Which is pretty disgusting. People give excuses such as "supporting the development" yet they miss the part that people already paid for the game and those who are playing AC are there to test and yet there is a giant pay wall to participate in the testing.
When Chris Roberts for instance gave his first response, he came off rather defensive and saying "they were doing the REC out of the goodness of their hearts" and how its costing them development money and etc. Yet we had this very same discussion back when the VD store was first introduced, hell, he addressed it in his $17 million Chairman letter stating that the VD store is not Pay2Win/Cash shop, but that is exactly what it has been for the past 8 months. Even in that letter he re-affirmed Ben's statement that they will work on a way for people to earn UEC to buy equipment/ships for testing in AC....yet what he stated yesterday is completely opposite of that. Then in his second post he defended REC stating how it's not freemium or Korean grinding like we were all saying, but it is Korean style grinding, at least with the current proposed system. There are plenty of games out there with a similar system such as APB, and people are forced to buy weapons to stay competitive because the grind is harsh. So there is quite a bit of disconnect with Chris Roberts and a lot of the community.
I'm just kind of shocked to be honest that CIG was going to continue to have the Alpha behind a pay wall which is disgusting but hey, he did state "by the time development is done this will be a $100 million game"...yet he asked for $23 million to make the game with all the current features *rolls eyes*....
Anyway I'm being too negative, a lot of people have given CIG some really good feedback on how to improve the REC system, hopefully they listen to the backers.
