There's not a single good game under their work, they ARE incompetent and should not be spared.
A developer can only work on what they're given (assuming they can't publish their own stuff.)
If Activision tells them they want a Tony Hawk game that uses this new half assed skateboard peripheral, theres only so much they can do.
If Activision tells them they want an HD Tony Hawk game that will be a downloadable discounted title that gets announced December 10th and released the next year in July, theres only so much they can do.
Basically, the biggest gripes about the game are the bugs. Bugs are the type of thing that take time to fix. Nobody just naturally develops a game without introducing any bugs at all in the process. A developer needs to be given time to fix them.
Another big gripe is the poor challenge design. There are a lot of cut and paste type challenges very similar to one another, and very simple. Again, this is the sort of thing that comes about when not given enough time to implement new ideas. We see this happen all the time with games trying to pad out their length.
When I played Tony Hawk HD it was certainly a flawed product but there was something there. It was far from perfect but there was a solid base to work from that a true, great Tony Hawk game could be birthed from.
I think if Tony Hawk 5 was coming out September 29th, 2016 we could have seen a true great sequel to the franchise, but Activision giving the game such a short dev cycle forced it to being this PoS we see today.
