well, this comes down to semantics now. Did you pay for W:ET? No. Did you play it? Yes. Thus, it was free to play. I also added ‘completely’ at the end, since there was also no micro-transactions or anything like that. All the mods, maps, models, skins, etc. that were added in, were all available free of charge.
Now I understand what you are saying - since W:ET was originally developed to be an expansion with a a monetary value attached to it, but at the end of it all, it wasn’t - it was released as a free download, rather than not being released at all.
Now any F2P game has an expectation of a revenue stream to recoup costs, this is course is more than acceptable, the problem however is that, IMO, this also brings with it lots of baggage to drive that revenue.
I’d love an option to just buy outright and reward the developer up front (well after a period to play and decide I want to continue playing).
One other thing that comes to mind here is how saturated the F2P market has become in the last few years. There are a lot of competing F2P games already out there already. They’re zero cost entry so players have little loyalty to pass over something new. Basically you have to set that hook hard to keep people playing and paying.
I don’t have a problem with an option to buy the game outright, however, I also don’t see a problem with a F2P model that makes a profit through micro-transactions or something similar, as long as the transactions don’t offer advantages over other players. Even if they offered the option of buying the game, it would likely still have ‘baggage’ attached for more constant streams of revenue, since they likely wouldn’t only rely on people deciding to buy a game they can play for free, just for some perks, even if the perks were generous.
