Does Telltale see iOS as just another place to sell their games and not a unique platform with differing needs to the desktop and consoles? Their decisions for it so far seem to suggest so.
All of their games suffer from 1.0 issues that you would think even cursory play testing would reveal—Puzzle Agent 2's audio problems being a prime example. Then taking months to update and fix those bugs.
Having separate iPad and iPod touch/iPhone versions, eschewing the more convenient for users, Universal app (calling the iPad versions HD makes no sense as they are exactly the same as the smaller editions. The HD moniker will make even less sense if we see a Retina iPad in March.) I understand charging £2.99 for one and £4.99 for the other gains more money than one £4.99 Universal version would. But when they are both EXACTLY the same game on the same platform it comes across as cynical. I could buy these games on Steam and play on both Mac and PC—incompatible platforms—for one (admittedly higher) price.
Not modifying the UI and interaction methods to better suit a touchscreen i.e. bigger text and buttons and, again in the case of Puzzle Agent 1 & 2, having the worst touch target implementation I've ever seen on iOS.
And in the case of Hector, releasing a Retina update to the year old episode one AFTER releasing non-Retina, episodes two and three (which are still yet to be updated)! They are primarily PC games playable in resolutions higher than 960x640, so unless I'm missing something they could all be Retina ready with minimal extra work.
Not using the strengths and unique aspects of iOS like iCloud saves and Game Centre achievements. Even when they are available on other platforms seems like more missed opportunities.
I don't want to use the word lazy because I have a good idea how much work it takes to port these games but I don't think their attitude to iOS so far has been very considered or even in the best interests of their customers. Telltale games on iOS seem to be an afterthought, available only to boost the bottom line. I say all this as a fan of Telltale Inc.
