Everyone must decide for themselves if a product is worth their own hard-earned cash and reasonable people are free to disagree. Not for me to judge.
It is worth considering, in my opinion, that OBD is the last company standing actively producing more WWI flight sim content. Nothing has been announced anywhere else, so if WOFF doesn't get the support it requires, there's literally nothing else on the horizon to look forward to in terms of WWI flight sim goodness. Speaking for myself, I plan to keep supporting them because I want to help put off the day that the most recent expansion is the final one for as long as I possibly can.
1000% with you on that one Hellshade. I got to enjoy WOFF for many years thanks to the generosity of the community here. I feel I owe it to OBD to buy some back copies of their latest offering when it comes out. There is simply not else left - and we are incredibly lucky to have a developer who actually caters to the offline, single player, sim fan.
