If its anything like GTA V then its well worth the money! As we all know you can spend hours and hours on Rockstar games and they are very well made , You also have the online mode where the story continues with friends so endless gaming. When you look at it from that point of view then you will 100% get £50-60 worth of gaming from it.
Fair points, but as someone who triple-dipped with GTA, PS3, PS4 and then PC, and who already owns RDR2 on the PS4 Pro, I don't think Rockstar would begrudge me looking for a discounted copy of RDR2 PC on launch day. Hell, they should be offering me a discount! And no, £55 doesn't feel very discounted for a PC title.
And besides, I need to save every £ I can on PC gaming since buying a 2080Ti.
