I have played 1-4 with my friend with no history of playing Silent Hill over the past year, and I want to play Origins with him too. We can't really do that with a handheld so our only option would be PS2. I've heard not so great things about it, but it is it worth buying used? Is it a completely butchered game?
I liked it. I still haven't been able to play through Homecoming all the way through because it is so far from what I enjoy about SH, but this game held my interest. It is not nearly on the level of 1-4, but it is a fun game at least in the vein of the originals.
I also imagine the game will be quite cheap to buy used these days, so it's not much of an investment.
I have 0rigins for PS2 and PSP. I like the PS2 port all right, didn't encounter any bugs or anything. The graphics are lackluster between PS1 and PS2 graphics, but it's still worth playing. I'd say go for it.
