Thank you for the excellent review! I'm wouldn't call myself a hardcore gamer, but I do enjoy deep strategy games (like chess) and military games that draw upon historical events. I've enjoyed several highly rated games such as Panzer Corp, Battle Academy, Pike & Shot, and also the non-historical but excellent Starbase Orion, but IMO TWR and TWBI takes the cake. So deeply satisfying on both strategic and tactical levels, that I deleted all other gaming apps from my iPad except for ShredderChess (which I'll always keep) and Twilight Struggle (which I haven't learned to played yet). If you like games that require thought and planning, then I highly recommend TWR and TWBI.
