It doesn't look THAT bad, some of the features could be used in Reloaded, such as the different brush types and the nifty way of leveling your floor at different heights. It doesn't look a patch on Reloaded in general though, and considering it's Unity based the FPS seems pretty low. Perhaps Fraps was limiting it to 30 fps, it depends on how the video was captured.
I have been a TGC customer since I got a demo on PC Gamer (or Format not sure) of Dark Basic. The scorpion demo wowed me. Compared to my prior programming on the Speccy and later the Amiga, this looked amazing. 3D In BASIC no less! Since then, I have got DB Pro and numerous addons, FPS Creator, AGK, AGK V2 and now Reloaded. All of them are great tools and each have their own quirks. AGK so far being the fastest of the bunch so far from my experience.
Compared to all the above titles, bar FPSC, Reloaded is by far the easiest to work with. At least as far as prototyping a fairly impressive looking 3D scene/game. No real coding is needed in general, and the scripting is fairly simple to get your head around if you have dabbled in any languages in the past when you do want to customize more. I can think of no other dev engine I have worked on that is quite as easy to delve into. I've played with Unity and didn't like the language much, although it only took me a day to get a fun little rally game going with a few physics commands
So I can't say it is massively harder than Reloaded to get into, although you do have to code everything yourself so obviously would be a tough job to make a full FPS game from scratch. Impossible if you can't code or lack the time to learn. There's no dropping a couple of entities on screen and just testing here, you would have to code the AI and such yourself. Not something even an experienced coder is keen on, let alone me, or indeed a fair number of Reloaded users!
I think we will see some good improvements in Reloaded's speed next update. Yes, it's been said before for other updates, and we have been disappointed. I think the time spent on this one so far points to TGC really wanting the next version to be solid and reliable. Faster as well, but we have yet to see what happens in this area until next week. I am not to concerned by multi player as yet, but I am sure a few will welcome it. I don't see the point until the engine is up to speed, apart from adding another feature and testing the water of course.
I think Reloaded looking pretty good so far, despite the obvious speed issues. It IS a small team. Just look at other game devs, even Indie ones. Not many have only 3 coders in it. In fact I can't think of any offhand, bar Banished, obviously there are more. Even then, most teams use an engine such as Unity or Unreal, Cryengine et al. Very few develop their own engine as TGC is, and if they do, they have a much larger team in general. So give them a little bit of credit and as said patience is a virtue. We are still in for a long wait before this is finished yet!
