Enhanced Version Windows?

[Blackcloud6]

I downloaded the free versions of both WinSPMBT and WinSPWW2. I played a couple of scenarios in MBT. The game is good but, of course, being so old, the graphics suffer.

I played both games for a long when they came out in the 1990s.

I wonder if it is worth buying the enhanced versions.

I can run the games both in windowed and full screen. In the window mode the graphics look better but the window is too small. I have a high end machine and can run the best resolutions. So my first question is, in the enhanced version are the windows at higher resolution bigger? If so, this is probably enough to get me to buy them.

The info page for the games states that the enhanced version has Opfire filters but I note the download version has them too. What is the difference?

Third question: One of the things that got me away from SP2 (now MBT) was that after a few years of playing, I determined it was nearly impossible to set up a proper over-watch. You could set up units to do so, but the enemy would just pick them off in his own turn; it was a problem due to the turn based nature of the game. Does the Opfire filters help with over-watch in anyway?

And lastly, what else is there in the enhanced version that I would want?

I'm a pretty hard-core wargamer and I like much about the SP system. I'm not likely to play it PBEM and I'm not interested in the tournament enhancement. The game seems to play well in the free download version so I'm just not sure about purchasing the enhanced version.

Thanks in advance for your help.
