Well, since the original ain't available anymore through legit means, I'm wondering if the game really is worth the asking price. Seems a tad too high.
It's a little nicer to navigate the menus etc. (as they're not scaled like they are with the original + widescreen mod), you can zoom in/out, and press tab to view doors/containers - that's about it.
It's a better product than the BGEE's, but if you're happy with the original + mods, I wouldn't say it's worth the price - wait till it's on sale for $5, maybe.
