Construct has more than enough power to create pseudo 3d worlds, I am using 98.9, and even without 3d box or all the fancy new z depth features, I was able to create a convincing pseudo 3d world for my upcoming game. You do not need any extra plugins (even 3d box) to make pseudo 3d in Construct, but you should be comfortable with a fair bit of math. Construct gives you the power of scripting without the syntax, a fast gpu accelerated engine, and a nice ui to make everything in. The rest is up to you! It wasn't made for true 3d because as everyone is saying, 3d is exponentially more complex than 2d. I do 3d modelling and let me tell you that 3d character animation is a job in itself. Also, the code for 3d games is ridiculously complex and mathy, and it needs to be, because there's just so much to account for. Conclusion: Construct isn't for full 3d, I i'm pretty sure it will never be. If you want a complete 3d engine, you will have to use something else unfortunately. 3d games are usually made by a team anyhow, because there is just so much specialization which is required.
