Unity has made a lot of headway in recent years. It is clearly a very good product if you have the money to spend on the pro version and the supporting additional software products.
Spend enough on the software and get a good team of users developing with it for enough time and the results are clearly or potentially likely to be very good.
Its a top of the range product in its class and really not expensive in that class. Its a diverse, complex, advanced and classy piece of kit.
Reloaded is not in the same class and does not need to be in any case. Rather than try and compete with the few engines like Unity around (none really)....
Reloaded is probably best suited for a different group range of users. If it can provide to them the tools they can take to within reason easily make a good game with then no reason why Reloaded cannot be as successful as Unity in its own class and with as many supporters as Unity in its own user group range.
Reloaded has a long way to go to get there yet but hopefully it can expand its user base sufficiently to help continue its development onwards for some time as a successful game maker.
Who knows then what the future might hold.
It has made some progress recently and the rest of this year should see some serious forward improvements and benefit unless something derails the plans.
