The only evidence we have is what dtg are saying. Effectively they blame Microsoft for the lack of sales. But other games especially smaller games get sales on xbox quite often and that article contradicts what dtg are saying. I wouldn't say dtg don't want to do sales but perhaps they should keep trying to get sales on the store because there is no restriction according to Microsoft. Also in tsw2020 there were a decent amount of sales. I managed to get East Coastway and RRO for tsw2020 on a nice sale last year so I don't get why in tsw2 there are no sales if there are no restrictions.
