Thank you all for contributing to the discussion. Two further points from me:
To get onto Steam, in addition to the development costs, I think HTC would have to invest in a marketing effort to re-brand AH3. I thought Gman brought up some really good points, and I looked up how many players WarBirds has playing on Steam:
the numbers are almost non-existent. So it seems Steam didn't really help WarBirds.
WB 2016 was released on Apr 2015 onto Steam, but they don't really have good brand positioning, if you ask me, based on their Steam store page. What sets them apart from the likes of WT and IL-2? It's hard to say based on their own branding, so that may have contributed to their lackluster performance on Steam. I think AH would have to make a strong case, if HTC were to use Steam, on their store page for what makes it different from other combat flight sims on the market.
This brings me to my second point. How would AH be able to attract the serious type of gamers that could contribute in a productive way to Special Events like FSO? I'm a little biased in this regard because, as I've said earlier, I think Special Events are what make AH unique in the gaming arena. I know I'm not alone in this because I remember seeing a poll on the AH forums which suggested there was a very large percentage of people that feel the same way that I do about AH Special Events.
I think it would be possible to attract the right kind of gamer on Steam and create a gateway for them to enter the Special Events world. The community is already here, but it may take greater cooperation of squads (who already have an interest in expanding their membership base) to help new players assimilate into FSO type events. Maybe there would be a special registration and training process for new players interested in Special Events that would also weed out the trolls looking to commit their antics.
What do you guys think?
