This applies to everything. If you see a product category where users are legitimately unhappy; then enter it, build something actually good, you'll be the biggest and richest in no-time.
Then steam reviews are the most accurate reviews there are for how likely you are to be happy with the purchase. I am much more hesitant to spend money on a game where I can't see the steam reviews for, so there is basically no way I'll buy a game on epic store that doesn't exist on steam since I am basically buying it blind.
And all game controller even works!
Steam is a serious value add on Linux.
With the added downside of less choice and/or delayed releases
Simply getting installer would not be option for most games.
I started using Steam in 2007 and it was fine. In 2006 there was still some residual animosity towards it but I think the tide had well and truly turned since the early days (and I think there were a handful of third party games on it by then too which I guess was something of a vote of confidence - a few were Source engine titles so they may have got a discount or kick-back from Valve, but not all were).
I thought CSS was the first release on steam beta? I remember playing the crap out of it, then the actual steam release happened, and it somehow turned into a laggy buggy hunk of crap for months.
Counter-Strike Source was launched some time in 2004 and then Half-Life 2 came along in November 2004.
but it got a lot better.
Epic had more money and time compared to Valve. and their store is still worse.
sure, Steam has an enormous moat, but that won't be the case forever, Epic should be ready with a nice platform to exploit niches that Valve misses
instead they hemorrhage money on things that does not make their fundamental position any better.
Eventually like it comes to all of us, there will be time to a new generation of game stores, or gaming devices.
It being a good service is secondary.
I don't see it going down any differently with Steam. It may take a dent and open up a competitor, but it won't do a move so catastrophic that it losses its leader status from that alone.
In what role-playing game?
