10-20 years ago it was normal, that video games hat a playable demow hen they were released. To promote them. Nowadays developers don't care anymore.
It's not that we don't care. In fact, I came into this bussiness expressly believing in demos and always providing them even when other developers did not. And making a demo is not hard for me to do. But I don't do it anymore. Why? It actually stalls people from buying the game.
A traditional buy cycle goes like this:
Scenario 1: Person A hear about the game and wants it. It is not on sale.
- They read some reviews, maybe watch a video or two, depending on their level of interest.
- They either wishlist the game or buy it, depending on how bad they want it.
- Derailment from demo: they either download the demo and don't play it right away, then forget to buy or wishlist it; or it remains a "this seems good but I need to try the demo first but I don't have time" sort of infinite loop and they never get around to buying.
Scenario 2: Person B hears about the game when it is on sale.
- They quickly scan some reviews, and see if this is something they want to plop down X money for.
- If it's something they are really on the fence about, they are most likely to either just let is pass, or want a really quick video impression.
- They either buy it, skip it, or if it just still seems to expensive then they wishlist it.
- Derailment from demo: they feel like it would be irresponsible of them to buy the game without trying the demo first, but that takes time and there are a variety of games they are interested in, so the likelihood of a skip is much higher.
At this point in PC gaming, demos have been widely shown to have a detrimental effect on game sales, particularly when put right next to the buy and wishlist buttons on steam. If someone is really looking for a demo and wants to come to our site to find one, then that's usually a case where they're motivated enough that I have no trouble giving them a demo. So a number of our games have demos that are not on steam, but instead are buried on our site a bit. It's not that we have something to hide, but the simple psychology of such a glutted marketplace creates an unfortunate situation in the majority of cases.
In the end, if someone is going to buy a game of ours for whatever price, and then they find out they can't run it for some reason, I'm super glad they can get a refund. Nothing could be more valid in my eyes. I'm super glad that system is there. Obviously there are problems with short games and so on, though.
My 2 cents.
