Well, I think Alpha Clones can pretty much sample all content within the game. However playing for free doesn’t entitle those players to have the ability to use every single item or fully engage in every single type of content within the game.
In my opinion the Alpha Clone state is supposed to be an extended trial period in which the player gets to sample and experience some of the opportunities in Eve and then hopefully buy a subscription to fully engage in those opportunities.
If Alpha Clones can access and engage in every single thing within Eve, then nobody will sub and CCP will eventually have to shut down the servers. Personally I don’t think the sale of PLEX, ship skins and apparel items would be enough to keep this game active. I believe it’s paid subscriptions that keeps this game alive.
Anyway, I’ve been playing this game for almost 10 years with an active paid subscription. I never liked the idea of F2P option or CCP increasing the Alpha Clone skill set afterwards. If you’re an Alpha Clone and want the ability to fully engage in all opportunities within Eve, then sub your account to Omega Clone.
