Normally I would get it here. But I read the Origin version is better optimized and patched to the latest version of the game. On the other hand GOG is DRM free. And lastly I have fund on my Steam Wallet. So... Where is the best place to get Crysis and Crysis Warhead?

Thank you for the help.

The GOG and Origin versions provide the 64-bit executable for the first Crysis and if that's a big deal to you, then buying either here or through Origin would be a crucial point. The version sold on Steam does not include this.

As to the version being sold on Origin being better patched/optimized compared to the other retailers - that I can't answer.

If the DRM-free aspect is all that really matters, obviously GOG is a guarantee but I believe you can also run the game if purchased via Origin without having to actually run the Origin client.
