I can say the DRM did affect my perception of the game.
My gaming rig is not connected to internet, which means I did not buy the game and therefore I have no perception at all...
Still very happy playing SH3 (NYGM 3.3 and Living SH3 v5) and sometimes SH4 for a change (RFB + RSRD) so I probably will have a perception in a year or so when DRM is off, game 10 euros and modders have solved the tons of bugs... (Like previous versions
)
