It really isn't. These are games that were already made, really old games. £22 is what I expect to pay for a brand new game that I don't already own, on release.
I would love to see Homeworld 3 and I hope the sales help towards that, but I am not paying £22 for this.
It's £11 per game (and you get the originals too), that's quite fair really. Clearly a lot of work has gone into these remasters so it's not just a simple case of writing them off as "really old games".
It is a shame there isn't a discount for owners of the originals to be honest.
How are they supposed to do that? The originals have never appeared on Steam etc.
