Drakengard is great. Drakengard 3 is relatively easy to find and feels more "modern", so I'd recommend it, but the other two games? They're only available through emulation in a shithole of a country like mine and I'm pretty sure most people would hate the gameplay. So I understand where you are coming from.

The same here, if you want to play lot of those games, you have to emulate them or got a ps2 and chip it~
That's why almost all I have ever played are ps2 games, outside of portable consoles~
