My last game, in which I suffered a UN defeat (it was a last gasp against an impending Spaceship loss, so it wasn't a surprise), presented me with a problem I'd not had before. (Monarch/Ottomans/Continents/70%/Small map.) Despite having plenty of funds, even spending 70-80% on research, it was taking too long to research and I was falling behind without being able to buy the techs I needed (they wouldn't sell at any price once the space race began). I was having to spend 20-30% on the LUX to keep from falling apart. I think the problem was just not enough luxuries - the map was generally resource-poor - but it still doesn't explain the problem. Had I been able to maintain my tech lead - and this is the first time I ever had it and then lost it - I likely would have won the Space Race. Is there an article (that I missed) discussing late-game research & strategies?
