apologies for being a bit gnarly.
there is so much more information about why Unity isnt here already other than it isnt here already.
its not like the info is hidden - there is info and answers in this thread too.
i get gnarly about it because people make statements as facts that are misleading or incorrect and they influence others to repeat or build upon those statements.
i cant talk on behalf of smiteworks and only know what has been stated here and on other channels.
some of the important stuff is:
unity has taken longer than initially expected
unity has turned into a much bigger job than initially expected
smiteworks was only 2 staff when the project was started
smiteworks now has two additional devs who are full time focused on this project
smiteworks now has two additional dull time staff who are focused on other parts of the business which in turn helps the devs do what they do
the current product has not sat still for 4 years while unity has been worked on
the current product has had multiple significant upgrades several times a year plus hundreds of small updates
the volume of content has grown massively over that time
the number of commercial rulesets has increased over that time
so why dont they just hire more people?
why didnt they hire more people earlier?
this is not a big triple A gaming software house - this is a small team who are growing in the right direction and directing their resources into the areas they know they need them to
and are growing at a rate that they can sustain
and that growth has been supported by the additional content that has been added
ultimately - whether we like it or not - smiteworks has the better understanding of where and why they spend their resources on the things that they do and they have to be able to balance expensive development costs against maintaining and growing the revenue to pay for those.
maybe unity will get here *too late*
but im willing to bet that it will get here at the right time and will simply be another step upwards for the team
oh and im sure there will be a bunch of sleepless nights when it launches and really gets stress tested and a whole slew of new bugs get found
and it will im sure still be worth the ride - at least from my perspective
have fun - keep gaming
