Kind of ironic that I post this considering that source was the very engine that I began mapping with. The engine certainly aged well but...every time I try to do something, every time I try to make something that could be called good. The engine holds me back.
Enter Unreal.
Unreal is complicated. So so complicated. I can't do anything other than make simple cubes. However; Unreal is the way forward. For me anyway. This year likely marks the last year I will ever use source. I sincerely hope that it gets updated properly. It should. It deserves it.
Once Valve update it, it will be make or break. If it remains fundamentally unchanged then I will stop using it. It's up to me to actually do work to make myself learn Unreal. There are a lot less tutorials but...I think that I'll managed it. My future career path depends on it.
