Hello,

I'm doing my new cross-plateform game, and i want to securate it from copying and hacking, 

So, I would have to know what are the technics that developers use to do that.

 

Thanks in advance.

Isn't it useful to make mail or sms verification? (or voice recongnition ph34r.png dry.png )

I'd recommend simply ignoring the pirates, most of them won't pay anyway, just lock them out of any online services tied to your game (including the support forums, automatic updates, etc) to keep them from actually costing you money and focus your resources on giving your paying customers the best experience you can offer them.

 

This.

 

Any anti-pirating measure will mostly just aggravate actual paying customers, that has to jump through hoops to play something they payed for.

Each step you add before letting people into your game will mean a loss of people bothering to go through the steps.

For a singleplayer game ? No, the normal pirate procedure is to simply bypass the verification code so it doesn't matter what you do, keep it simple to reduce the hassle for paying customers, if you want to add complexity to slow the pirates down that complexity should be behind the scenes(paying customers shouldn't have to know its there). (obfuscated code, redundant checks, encrypted files and other measures to make bypassing the verification more timeconsuming) but it takes significant effort on your part and probably won't buy you more than a few days or even just a few hours,

 

If you absolutely want a decent DRM scheme for a offline singleplayer game you should just license something like Tages instead. It is pretty obnoxious to crack(and has to be cracked individually for each protected game) which is good but its driver has also caused a few really serious issues such as bluescreens on system boot for example, requiring a re-install of the OS or a manual uninstallation of the driver from safe-mode which is pretty darn bad. (especially since only paying customers have to suffer from those side effects) so its a trade-off. (AFAIK the latest version of Tages is stable and their major problems are mostly in the past but DRM kernel drivers are always a big risk)

Thank you SimonForsman!

 

I'm really convainced by your arguments, But are them also valid for mobile games (Android, windows phone, iOS)?
