I suppose we have been back and forth on this topic and I'm going to surmise and be honest, please note this is not to be misconstrued as an attack at Unity neither does it mean I'm not going to continue with Unity. In essence UE4 has done a lot right, which Unity should take notice of. I would like to mention, it's great that Unity are listening. Unity 5 vs. Unreal 4: I'm going to leave Unity 4 Pro out of this, because as of the moment it doesn't really compete with UE4. Whether we are talking in terms of monetary value / feature sets or performance. Please anyone, feel free to disagree add your own 2c as I'm going by my perspective in regards to what we are doing as we all are. Let's talk money A hot debate no doubt and something that can really only be answered by Unity, you know what profit margins are available. Unity knows how they can restructure pricing formats, I'll keep this short and sweet there needs to be a way of cutting the cost of some feature packages to at least remain somewhat competitive. Even if it ends if with Unity Free / Unity Pro and Unity Extreme, Extreme being the full blown suite of all your latest and greatest + middleware like UE4 are doing. In UE4 it costs about the same as high spec BMW + royalties if anyone is asking.. So Unity definitely has a +1 up on UE4 for that.. Also a debatable point is upgrade costs, you should not hold back features due to upgrade costs. Even if you base upgrade costs on support!. If you ditch support for a cycle then it's a good enough reason to upgrade. It's up to the user whether or not he want's to upgrade.. Feature Sets I should add a little chart in here, but anyway: Pro's for Unity 5: PBR Enlighten Audio Mixer Level streaming? (Depending on what you're doing) 64-Bit Editor Reflection probes UE4 has all the above besides audio mixer and enlighten in the $19.00 edition. Bonus features in UE4: Cascade Visual Effects Material Editor Blueprint Matinee Cinematics Advanced Post and Anti Aliasing (TXAA) Better terrain system So Unity isn't that far away, although many of the features in UE4 would be VERY handy. I'm not familiar with 2D but from what I've heard Unity is pretty good in that respect. Bugs and feature releases This area needs some attention, we are pro users and can afford the support monthly costs although as of the moment I haven't been inclined to pay out for it. No way should a GUI take that long, bug fixes should be sorted in the space of a month not a year I'm sure people on this forum can give you MANY examples of this. Try and become a little more pro-active in this area, I'm sure a big portion of Unity Pro users want quality over quantity. Beta Access I know a few developers working with pretty large publishing outlets, myself included that would rather have a beta than put up with constant issues due to Important, non graphical, nothing fancy engine operation features lacking like the 64-Bit editor as a prime example. Some of us NEED that Beta access, it's a shame when we don't really want Beta it's more of a need. Final Thoughts I have a team of 15 now, 10 of them have been pulled onto a FPS project with Unreal 4. I'm with a skeleton team developing this game in Unity because of two reasons: My staff were constantly asking why we are using Unity (Reason is I did a concept by myself in Unity and loved the workflow). The other is our financiers will not sign off for any more licences, neither will they sign off for a support contract and give me the ultimatum that if the Demo isn't successful then I switch engines never to look back. UDK released their 64-Bit editor in May 2010, not Unreal engine.. UDK! It's hard to expect the A, AA, or AAA sector to take Unity seriously when functionally is severely dated and often times half baked. Why have you been working on Enlighten when there's a ton of other things that needed to come before it? The Indie market is 50/50, other sectors still don't seem too keen either. Expand Unity's horizons and money will come along with it. I want to finish off on a lighter note, Unity's workflow is incredible. You guys do a great job at sensing what an Indie needs for rapid development. Just look at all these post's we obviously care enough to spend time posting about it. Indifference is the most worrying situation to be in..
