Unless there is something missing in the comparability between the game engine of choice and what C4D can support then I cant see any issue to go as far as get allot of negative feedback.  There was a issue a while back with smooth groups, I believe this is now working fine.  Ask those who give such negative feedback if its based on technical reasons as to what comes out of C4D is not meeting the specifications of The Unreal4 engine, or if its preference? HQ characters comes from high quality artists in the pipeline all the way from concept, modelling, texturing, rigging, animation. To me C4D is a set of tools, like Zbrush is, MODO is, and for what it lacks I have another tool to make up.  Maya is without doubt the tool the industry go to, so its only fitting that thoes who want to get into a gaming industy they learn the tools for the job.  If your a student looking to get into the gaming industry then go Maya as your fit into most studios pipelines.  I can honestly say that iv created content ready figure in a $1.99 modelling application DAZ3D Hexagon. Now the reason why I would say while you can do it in C4D id recommend you dont is down to its lack of modelling tool symmetry, I often need to tweak a model even after I have done the Uvs, in C4D that is not possible as you got to cut your model in half, bye, bye to your Uvs. and point order.  Some modeling tools dont work so great such as bridge, there is no auto quad fill, and the knife tool needs some attention which Im sure it will very soon.  Its Uv tool set while capable dont support UDIM, and its very slow to use compared to other stand  alone Uv mapping apps.  Could I make a character from scratch in C4D alone, I certainly could, but it would take me way longer than in MODO, but the results all be it the UVs would be the same. Go to MAXON site where it talks about the compatibility for games, and try to get some deeper understanding to if Maya has tools and features that make the process easier such as the Viewport 2.0, VR to walk around a game level, direct transfer between the apps this is where id look.  If anything id say there i more HQ artist in the gaming industry that dont use C4D that just putting it down to the tools.  Maya in the wrong hands will output bad results.

Can you upload it here, it's hard to tell like this?!

There is so much hate towards Cinema 4D that is coming from Maya / Max community for no good reason and I am not sure why. Maybe their are jealous on rock solid stability, I don't know, but as a 3D modeler I can assure you that Cinema is more than capable of producing high quality stuff, just take a look at some work in the gallery. ;)
