All things considered, and I know I'm new to Rising World, but the development cycle seems fine to me. I mean, yes, everyone wants more stuff - content, things to do, crafting, items, etc... Maybe even some prefabs to explore. I don't know how long RW has been around - according to Steam it became available in December 2014? At any rate, looking at how much you can actually do, and how big the world is, and the fact that it's random / procedural generation and by the looks of it pretty much infinite - I'd say the pace for a very small team is about right. I mean, this isn't my first early access game, nor is it my first alpha (I used to do alpha / beta testing starting back in 2000 and for several years), so I kinda know what to expect.
Is it perfect? No. Is it coming along quickly? No. But it's also not really that buggy compared to other currently-available titles. I love the whole voxel / destructible world thing, but I hate blocky worlds. So I've never played Minecraft or any other similar games. I do have 7 Days to Die (for my zombie killing fix), and Space Engineers (for my building / flying fix), but Rising World fills another niche, for me anyway. And that's pure exploration with building.
Sure, I look forward to more content, more things to do, and more to explore. But the game isn't broken. At least not for me. I played for about a week straight with my son, and we both enjoyed ourselves (he's a bit mischievous so he enjoyed hitting me with his axe / pickaxe then running away). We built a small base, then started working on a much larger structure - a mansion of sorts. We didn't run into any serious bugs other than I couldn't see the animals he aggro'd. But that's minor, and there were no crashes.
So, Red, keep on keeping on. It's coming along - slowly but cleanly. All things considered, I made the mistake of buying into The Dead Linger, and have watched from the sidelines as they went through 2 major engine changes, and 2 years later that game is pretty much a waste of hard drive space - even to the point where its current state is actually much worse and far less filled out than it was 2 years ago.
Anyway, I'll stick around and be patient, and I look forward to the new biomes coming soon.
