*(Whether it is worth it for you, only you can say. If you've not played it in the years you've had the discs sat at home, why would you play it now with a download version? It'd save you the hassle of having a Playstation set up, or an emulator -- but whether that's worth the price tag is something only you can decide.)*

The minimum system requirements on that site are:

- Microsoft Windows XP/Vista/7 (32/64-bit)
- 2GHz Processor or faster 
- 1GB RAM
- DirectX 9-compatible graphic card

If you have an internet connection and a suitable PC, you can download the game again and play it from where you left off by taking advantage of the cloud save storage. You will not be able to play this version on your mobile phone. The "with just an internet connection" part is strictly talking about transferring save files between computers with the Square Enix Cloud Save function.

Finally, this version is the same as that [found on Steam](http://store.steampowered.com/app/39140/). If you already use Steam, then it may be preferable for you to buy it from there.
