I went to the university from 1989 to 1994. I bet some of the books I bought can be used today, with some exceptions, like auditing or accounting because some acts or laws exist now, like SOX, or advanced biology or chemistry courses.
But take math/algebra, pre-calculus, calculus, history of PR/USA, classical music, maybe thermodynamics, and so many more, I bet they haven't changed a bit. X^2+2XY+Y^2 while X=3 and Y=2 or the time it takes certain metal component to heat is still the same...
...and I am a fanboy of Ubisoft because most games they publish are excellent (Splinter Cell series, Prince of Persia series, Assassins Creed series).
Darn, I keep ALL of my games. I still have F22 lightning3 from 1996, F22 F16 MIG29 from 1997/98 and Thief Gold from 1998 in mint condition, among many others. So, if I buy this Anno 2070 and keep it like I do, when I upgrade next year my video card or CPU/MoBo, there goes another activation, then when I fresh install my OS mid year to keep it running smooth, there goes another one... That's stupid.
That means that I might buy all their games but install/play the pirated ones? Hmm! I don't know. I can keep clear of this game, like I did with BF3 and its Orion problems.
Still with all the negative talk about Steam, it is good for me. And since I never go to my friends houses to play because 95% of the PC's in Puerto Rico can't handle my games and there are almost no hardcore PC gamers, I guess I will have no problem with Steam banning my account. (seriously, Steam have noticed when I use a different browser to access my account and they send me emails to change my password just in case... great service uh?)
