We will not be doing paid DLC. So that is all really kind of a fun hypothetical discussion that won't lead anywhere.
These updates - on any platform - do cost a substantial amount of both time and money resources - I say that as a matter of course, not for sympathy or anything. Rest assured that Re-Logic keeps a close eye out for what is going on across the franchise and then makes our thoughts (good, bad, and ugly) well known to 505 Games. To-date, they have been fantastic in making some pretty sweeping changes as a result (complete overhaul of Customer Service, ongoing complete overhaul of QA, etc.). Sometimes, those changes take a good amount of time to come to fruition, but the fruits have been and are still coming from that collaboration.
The catch-22 of "don't give release dates" is, of course, the never-ending spam about "when is X coming" - trust me, I must read that about 100-200x per day either here or on our social media accounts. The other side being that game development is a squirrely beast to pin down - it doesn't really care for your deadlines and has a nasty habit of tossing issues at you when you least expect it.
Now, I think we were all in agreement on the more regular communication - and, as I noted, I checked back with everyone....and everyone seems aligned on doing far more regular news updates (with the understanding that the amount of news in each update will differ based on what there is to share).
Then there's the 3DS/mobile version that crashes every 10 minutes, has tiny worlds, no online multiplayer and very little hope of ever reaching 1.3... (yet the 3DS version is the most expensive on the market)
Mobile has issues - but that is a gross hyperbolic statement. There are some people that experience what you describe, and the team is hunting that down (as I noted elsewhere, if people can file tickets/provide logs and info, that search would go far more quickly) along with working on the next in what has been a steady stream of fixes that have come on a pretty regular basis since the start of the year. They also just added PC Small worlds.
3DS does not crash "Every 10 minutes" - perhaps it does for some group of people(?), but far from everyone. I've had maybe 1-2 on mine....and my kids (each of whom play daily for hours) have had maybe 3-4 each since December. Not saying that ANY crashing is good or desirable - and the 505/CG guys are working on a ton of fixes to add into that content coming in the update mentioned.
Pricing is a complete and total red herring that has been beaten to death in many locations. As I have noted elsewhere, not one single platform manufacturer (Sony/MS/Nintendo/etc) sets pricing based upon what a game costs on some other platform. Typically, it is set vs "comparables" - similar games on the same platform. For the 3DS version, that means it would be set based upon other 3DS games - not what Terraria costs on PC or anywhere else. 3DS is ultimately paying for portability to me. I personally cannot play the mobile version all that well (I struggle with the controls, maybe I'm just too old
) but I find the 3DS version to be quite enjoyable to play when on the go.
The funniest bit on pricing to me is always comparing to MC, where we are generally quite similar (again, comparables) - except on PC, where Re-Logic have kept the price stable at less than half of what MC costs - and then we and/or 505 get yelled at for pricing elsewhere because PC is cheaper. Think about that for a second. Anyway, that is getting off topic...but I wanted to once again deal with that before it derails the thread further.
