Flew under the radar. They added a campaign like two years after release. I played a bit of it, the gameplay was good but the campaign did nothing for me.
Next game in the series will be the single-player focused Dustwind: Resistance:
However the team behind it is also working on a new mini-campaign for the original Dustwind called "Two friends".
I don't understand why the same doesn't appear to apply for Fallout 3. I only played it on launch and it was horrible with frequent crash to desktop where I loosed a lot of unsaved progress.
Fallout 3 gets a pass but New Vegas does not and it's a bit odd to have different standards like that.
Did you see that they released a new patch yesterday because the ten year anniversary? And they will add a turnbased mode later this year. That even makes me want to replay PoE and finally complete the White Marsch.
I played it twice, the second one was only in order to get the achievement for it. It has a nice feeling to it as you can't save and have to finish it in one sitting. It's only 45 minutes long though.
