Several times I managed to play with cryengine sdk, which comes in special editions for crysis and farcry games. I don’t remember if it’s lua or c+, but the functionality of the engines is low, it’s impossible to complicate the frags, there are practically no tutorials. Its pros: I will not reveal the secret, but the graphics here are still nice. Good sounds, voice acting, nice to shoot. Some cons: -actually there is no plot, the game is just a benchmark. All these soldiers swallowed up by aliens are more likely to cause laughter -poor cliff jumping mission - after half an hour the game gets boring -something complete silence, then you are wetted from all sides
