I also have the HIB version. If Play Store's version is DRM-free version or not I don't know but I doubt it is.

That's an interesting question. It's not trivial to transfer the Google Play version to another device that doesn't have Google Play, but IIRC it's possible. I may be wrong though. Personally I'm fine with Google Play since it's such an integral part of Android that I don't envision using Android without it.

I think both systems are fine and can usually do rough conversions in my head without much trouble. The only metric system scale I don't like is Centigrade (Celsius). While perfect for scientific uses, it is too narrow for talking about the weather. A range of 100 degrees on the Fahrenheit scale corresponds to only about 40 on the Centigrade. So there is a lot more nuance in stating the temperature in Fahrenheit - you can talk about a 60F degree day versus a 70F or 80F or 90F degree one and get a real feel for the difference, whereas saying it's 15C, 20C or 30C degrees just doesn't express as much. Similar to using metres in place of feet, the unit of measure just covers too much ground in one step for casual human usage.

I'm more thinking that if we have two Android devices which have different Google accounts (e.g. one with my account, and another with my gf's), can the same game bought from GooglePlay be installed and played on both?

Also I was thinking that the newest Android versions apparently support having several accounts on one Android device, so is the game available for all the accounts on that device?

Needless to say, with the HiB Android games there are no restrictions, you can freely install the game to all your Android devices, no matter whose account is active in them.

I haven't tried it myself, so who knows, maybe the apps and games bought from GooglePlay can be transferred easily to different devices with different accounts, with no strings attached. Does it save some .apk file somewhere in the depths of the device?

I bought a game on my wife's device using my account, and I think it downloaded there just fine. I did it because my Defy wasn't compatible with it and it was on sale, and I was sure I'd get a tablet later.

So it should work. Android 4.3 introduces profiles and users, and I have no idea how this inter-operates with multiple accounts.

0C is 32F, and the boiling temperature of water is 212F. So a whole number scale as well in that system.

All a matter of opinion. But I maintain that more shades of distinction means more subtly and more effective communication. I am strongly motivated by aesthetics though, so this could have more primacy for me than others. For example, I like having colour definitions like teal and aquamarine, and don't find saying "bluish green" and "greenish blue" a suitable substitute. So saying that decimal values make Centigrade just as expressive as Fahrenheit doesn't convey for me. You may as well say it would be fine for Centigrade to put freezing at 0 and boiling at 10, and describe the temperature outside as 6.21. The human mind works best with whole units, and the more expressive those whole units are, the better the system for human use.

Didn't I say I was fine with both systems? I'm a scientist, I know the functional value of the metric system, and I'm not opposed to it. A lot of calculations are far simpler in metric. I'm saying that the Imperial system works better at the casual human scale, because it describes things in a more readily graspable set of human dimensions. This has been the main obstacle to adoption of metric in America. Not because it's foreign, but because it is less human oriented.

Its not as though we refuse to use the metric system in America. Most rules and many of our thermometers have both scales side by side. Hardware stores carry screws and such in both systems. At least in my area, people even use meters just as much as yards to describe that distance. Neither Meters or yards get used all that much though, as people prefer to describe things in feet.

How do you get them running on Gemrb? Do you just copy the BG1 or 2 folder over to the android tablet? There's also that config file you have to setup, is there a setting somewhere I am missing? It seems to go to a black screen and then dump to the desktop.

I'm presuming that's the general idea. There's probably more steps to it than that. Did you check GemRB documentation?

The documentation for the android leaves something to be desired, unfortunately. I am waiting for the Enhanced Edition, because I just can't get it running properly on my tablet.

I'm half hoping it wouldn't be deviating so far from the general GemRB install. Hmm...

"The sarcasm is strong in this one!" :-D
