Ah, that's a shame. CA/Sega really did a dumb job with the whole "only release it online" thing. The Fourth Age is fun, but really not superior to LotR:TW (unlike what they claim). LotR has better skins and a better map, and much better unit stats...whereas Fourth Age has some new voices, better buildings, and is more true to what little lore it has to base it on. I still play LotR:TW more than TNS:TW, though, simply because it's so much bigger and there are soooo many factions that it never gets old. I'd say it's worth getting Alexander just for it.
Anyway, enough of my babbling. Keep up the good work.
