There are several things wrong with this thread. The first one being the word 'already'. Forgotten Hope was founded before the release of Battlefield 1942 and therefore is at least 11 years old. If you know of any mods that have existed for that long without switching over to a commercial model I'm sure it can't be many.
The second thing is that making a thread with the words "mod dead" in it is probably the best way to keep new players from downloading it.
Now, as far as I can tell, even Forgotten Hope 1 is played pretty extensively still, so I'm pretty sure Forgotten Hope 2 will have a player base for some years to come.
Now as for the development, while I am still listed as a 'developer', I haven't actively participated in the development of Forgotten Hope since the release of 2.45. I only visit the internal forum sparingly, so I don't have the full picture of what is going on.
The development of the mod is by no means a continuous process, it has periods of high activity and periods in which pretty much nothing is being done. It all depends on the people who are working on it. This isn't a commercial enterprise, developers have jobs or studies that require their attention and these things are not always regular and predictable (one of the primary reasons we cannot predict release dates).
While periods of low activity are normal, the mod is currently in a period of no activity or certainly the lowest activity which I have ever seen it at and I've been with the mod for a long time.
However, the mod's development infrastructure is still all functioning, so the only thing it needs is active and enthusiastic developers who are willing to spend their free time on the mod. So don't lose hope. We are in the middle of the summer (I don't think there are developers on the southern hemisphere) and people are spending their time outside and on vacation. I think and I hope that in the autumn the few remaining developers with the assistance of the extremely dedicated core of beta testers (who in essence are semi-developers) will get together again and continue the development.
I know for sure that it would be too much of a shame for any dedicated developer, active or retired, to let all the amazing content that has not yet been released go to waste.
