Most people who would be interested in this game do not give a shit about SEGA or their history, they just care about the IP the game is based on, and usually they do not care how the product turns out regardless. When I was like five I loved TaleSpin on the Genesis, but in actuality it is easily one of SEGA's worst games of all time. At the time it came out, I could not care less about what other people thought, I just knew that I liked the IP and that I could play the game with friends, so I enjoyed it.
Comparing this to a rushed plumbing job does not make any sense. In the case of that you could get sued, last I checked no one ever got sued for making a shitty game. Budget cuts do not always hurt games either. Sonic 06 took bundles of money and three years to release unfinished, poorly planned and in some cases considered one of the worst games of all time, while something like The House of the Dead Overkill had barely any money put into development and was made in just over a year, but turned out to be one of the highest rated and loved Wii games the year it came out.
People can also improve. Naughty Dog for instance started out as one of the shittiest game developers around, but now they are easily some of the best in the whole world.
Of course I am not trying to soften the blow of Simon Jeffrey, but what does this all matter in the end regardless? Who on this site even really cares about Thor? When Barry posted about it on the front page he did not even know the origin of the mythology.
