The whole point of a product like Reloaded is to give indie developers, very often one man operations a hand up the ladder, ahead start. In fact much more than that is needed to make a decent computer game. No matter how much help you can get of any type it will still take a very long time to make a good game worthy of the title. Some years I guess - given that yes you may want to include a lot of your own content and or put your own slant on existing content, as well as developing the design, planning, story, levels, content, programming/coding, music, interface, cut scenes and much, more.
Nothing stopping anyone who wants to make all of their own content from scratch from doing so if they have the knowledge, skills, time and money and still a lot of it. Some years at least I imagine.
Yes you can create a game of some sort in a reasonably short space of time and those that want to do that can go further with any level of bespoke game creation for assets and so on they desire. Spend less time or more time depending of your circumstances.
That again is the whole point more people have more choices and Reloaded will have more users and more games will be made with it. Short Games, Long Games and games of different types and qualities depending on ones point of view.
Out of all those games made few will be top games BOTB and alike. Few users will want to spend years making a game by making their own bespoke game and content from scratch. The majority will want to Use Reloaded because it is easy to use and gives them a route to a speedy pipeline to end game deployment.
No idea why anyone would want or choose to have to spend more time and resources making a game than they have too. If anyone wants to volunteer for that then they can do so and those that don't can also make a game inkeeping with their own abilities, resources, skills and time and so on.
Helpful internal features can help everyone equally - a benefit for all users. You don't have to take advantage of them if you don't want too. For many it will be the only way to success or just make a simple game and enjoy themselves rather than being frustrated not achieving anything at all for reasons which are often personal and cant be discounted and or quantified by anyone else.
Tools like Reloaded empower more people to achieve more themselves when it would otherwise be impossible for them to do so and that is a very enviable achievement in itself.
That is the bottom line - Reloaded is a tool to help people make games - the more people and the more games the better. Some you may like, some you may not but then that will always be the case no matter what. Some creators or developers often wont like their own games as we well know having made them - self satisfaction is not easy to achieve no matter what. Its a personal thing. Still lets have them.
Don't make the mistake in thinking that using Reloaded to develop a game will be a walk in the park or that it will make a top title for you out of the box without a lot of hard work. Depending upon your point of view that may for example require AI to think like humans and that is a long way off for indie developers and Reloaded too. You may/will need a lot of skill in various disciplines and areas of game making and much programming/coding perhaps to achieve that and much more and many other things seen in top games. It wont be that easy no matter how helpful Reloaded becomes. I have not seen too many top notch successful games yet made with any indie engine and that is not likely to change for the same reasons as always have existed. The bar is now much higher by and large - though you don't necessarily need an easy to use, sophisticated expensive and advanced game engine and end game to make a successful one but in the main it helps a great deal. Importantly Yes the internal features and pipeline needs to be helpful and they and the whole stability smooth and helpful or indeed you can spend more time in frustration than actually making anything and the years can drift by so as said a walk in the park it may well not be quite yet.
