can I use a splash screen with Unity logo in a game made with Gamestudio, to not to look so amateur?

Who care wich engine we use, customer is only interested in the quality of the final product

@sivan
you can put the Unity logo next to the gamestudio logo if you want that
even tint the background black if your getting serious...

@JibbSmart:

I've been working in Graphic design, industrial design, Archviz, product demos and small/educational games for a living for the past 15 years, 8 or 9 of which I've been a freelancer, i know exactly how to present to my clients and 'made with personal edition' is unsellable.

Unity 4.x released 2012 so your company budget (you!) should have had tons of time to build up and upgrade fund. The complaint seems to be that a software company changed their model of business to increase revues. Autodesk must have also been problematic for you when they changed as well.
Software companies change rules, design and business models. This is a fact of business. You accept and work with it, find and replace it, or build it yourself. Complaining is not part of a successful business plan.

@Nuclear Winter: I'll take your word for it that that's the case in your particular industry. That's not an explanation, though.

I shouldn't have left! this place is going down the tubes ! - I was such a fanboy, what is there to be done?!

Why did you leave anyway!? :<

Less bitching, more doing, ya shitlordswhiny little bitches.

Well i lost everything i was working on inn A7 and my licensing file. And i felt like turning over a new leaf, teach my self backup routines and focus on music for a while. Found my code again on my psp (of all places), I would really love for this Engine to get a second wind, I mean its big part of what made me who I am. I feel like we should try to get more people to come by and check it out, but its hard seeing as the other guys have big teams and marketing, and comprehensive free versions. - Maybe (in the spirit of what sid is saying) we should get together an make some real neat demos? push it to tha limit if you will ? Idk but there must be something an engaged community can do?
