I just checked Steam and as of this writing there are 1,115 Mac games there.

Here's a bunch on GOG. I didn't count them all: http://www.gog.com/games/##system_osx=106,107

The Mac App Store has tons of games including some well known ones not on Steam such as Tropico 4, Total War series games, Bioshock series (latest is on Steam), and just too many others to list here. Oh yeah, both Baldur's Gate and Baldur's Gate 2 Enhanced versions are on the App Store also.

Blizzard on Battlenet offers WoW, SC II and Diablo III

Turbine Entertainment offers LoTRO and DDO on their site.

The Elder Scrolls Online will be releasing on day 1 for Macs.

Some highly anticipated kickstarter projects will also be releasing for Macs such as Torment, etc.

Let me just check my own library here...

249 OS X native Mac games
14 OS X games setup with Cider (by the game developers)
97 OS X games setup with Wine by me (and GOG) including too much awesomeness to list here.
36 OS X games setup with Boxer by me (and GOG) all awesome classic titles
----
396 games in total that are currently in my backlog to play on my Mac. There are even more than I just listed here from checking my database but those are in the maybe/someday bin.

And that does not include another 100 I plan to play in a Windows XP virtual machine with Parallels and 40 left for Bootcamp (backlog) before I ditch that since good new stuff for Mac keeps releasing at a pace faster than I can keep up with.

Now, it is true that some AAA releases I might want to play do not release for Macs. Playstation 2, 3 and 4 is the answer here and for me I am working on my library of PS2 games currently. Great new releases I cannot get for Mac, I will often be able to get for a PS4 eventually if I ever catch up around here.

So between the Mac and a console I honestly see zero compromise in not having Windows. The only reason I keep it around on my Mac at all for now is just to play legacy stuff I owned before I got the Mac and when I am caught up with that - goodbye Windows. There's just no need.

Just sticking to computers though and forget the console, I've got almost 400 games to play and it isn't like they are not good, well received and well known games either. Steam has over a thousand Mac titles and there is more they don't have on the App Store and Origin and Blizzard, etc. So I guess the question might be how many games do you really need?

No platform has it all. Windows for example does not get Xbox, Playstation or Nintendo exclusives. The consoles do not get all games on PC. Mac is a smaller platform. It does get less releases than Windows certainly but it does get way more than anyone could keep up with who has a life outside of gaming that is for sure.

So it isn't really accurate to put down the Mac platform as sucking for games or being limited because honestly it doesn't suck at all and all platforms have some limitations. The beauty of a Mac for those who prefer them but do want access to Windows games is you can use Windows too if you want. I do not prefer that myself but the option is there for those who want it and choice is always good.

I'm not trying to convert the world here but I do like to let people know Mac gaming is not some barren wasteland of iOS ports on the App Store. We get a lot of great stuff which I won't list out here but you can see for yourself by checking the places I've mentioned above. By the way, some of those iOS ports only on Mac are pretty fun. :D

lol wow, well htat's impressive, had no idea. Well I prefer not to game on my mac other than SimCity 2000 and 2013, but it's good to know that there are more games comming for it, lots more as it seems lol.

Dell buys Windows OEM licenses in bulk from Microsoft. One of the caveats of OEM licenses is that the software reseller deals with consumer support when it comes to Windows. So Microsoft is right by directing you to Dell to solve your problem.

Now, in modern laptops the OEM license is tied to your motherboard, so you don't even need to type in any CD-KEY, you just install the Windows Core Single Language (or Pro if you bought that) and it won't even prompt you for a Key (its embedded in your system).

The problem is that Dell doesn't supply disks anymore with laptops, so you would have to get your hands on a copy of the windows OEM for it to work (and no, it wont work on regular editions of windows even if you extract your activation key with R/W Everything or any other program... I tried it since I had a bunch of original Windows CDs from my desktop systems).

In my case, I... well, I may or may not have found myself a copy of the OEM image by maybe not-so-legal means, if you catch my drift, from a link posted directly on the official dell forums no less. But I think you can request an OEM disk from Dell or ask a Dell technician to install it for you (most likely by paying them money).

So, reinstalling from a clean OEM image might be worth a try (has to be the same version your laptop is eligible to). If this doesn't help you, though, they may have messed up your system and forgotten to embed an activation key on your mobo or something. In that case, pester them to fix it, most likely by giving you a new laptop.

Be sure to back up anything and everything before doing this.
