Technically speaking in theory Leadworks is superior to Reloaded in its own features for what it does which is not a lot compared to higher end engines. Most indie engines suffer from the same issues they have always done so no need to restate them. Its not really expensive so you cant compare to approaching middleware engines like Unity for range of features and so on which far exceeds most low end indie engines by a major order of magnitude. They are a different league altogether.
Problem is they are all of little help to small indies. Why - well because the are expensive to buy full versions of or are expensive in terms of the resources, skills, time and so on needed to make a game with them too.
Reloaded is in concept much like classic in as much as it is intended to help you make a game easily and quickly which no other engine does in any kind of relative terms to the Reloaded engine. All are trying to make themselves easier to use whilst providing more features, platforms and so on and most will have more of the platforms at least than Reloaded. Not much help to you if you cant make a game with them in the first place.
Whether or not any game engine is of any use to you can be assessed in the first instance by looking at them and the games made with them to date so in terms of a Shooter engine with AI and any level of sophistication of that at all then you can see their are still today very few games actually published commercially at least with most indie engines (disregarding their price completely). Something that many indie developers aspire too.
How many games complete fps games (or other) can you find made successfully with Leadworks. How many available to play demos of games for example from their or other web site? Unity does have a largish number of games published of varying qualities you can see and demo. It continues to take large strides forward obviously due to it own success in recent years placing it at the forefront a position it holds exceedingly successfully.
However most other engines are beyond the use of the average Reloaded users for obvious reasons of being small developers with few of the necessary skills and assets to make a complete and successful game - not being disrespectful but its a question of maths and the level of all kinds of resources needed to make a quality, professional type, large and successful complex game which everyone would like to do if possible. Its in our nature to want to do well and have such satisfaction of achievement and success and not failure which is why we keep at it. Its what drives indie game makers apart from any creative enjoyment and satisfaction of playing a game they themselves have made no matter how large or small or successful. That's not easy to do with any other indie engine.
Reloaded has some considerable potential perhaps but its at such a low end early development stage that no one knows yet what it will be able to achieve or not when it comes to actually developing and deploying games for small indie developers. We can only catch glimpses and dream perhaps not too seriously of what it might eventually become.
There is so much that could potentially be included if the engine can indeed provide and sustain it even at accelerated development it may be a very long time before it becomes a mature, stable engine on which you can rely to provide a wide range of features and functions leave alone deploy to other platforms which is just about too far away or impossible even to consider right now I would think.
Its an engine starting birth in its first year. A Baby and a lot of complex things to learn and manage before it becomes an Adult ready even to diversify to things like other deployment platforms which may never happen. Getting to a stage of being a full featured engine that you could make a variety of game types with at anything like a pro or commercial level at least on the Windows Platform alone seems like a long way off yet. There are literally thousands of features, functions and things to integrate to get there as its a long way behind only just being born as it were. A lot of catching up to do even to get to its teens leave alone become Mature.
Leadworks has been around a while and so too most other indie engines of note. Discounting Classic, Reloaded is the new kid on the block which has to grow up and prove itself to its peers and users alike.
We have to wait and see as always I am afraid.
