Georgia paid the price for a quick turnaround between games against Uruguay, according to their captain.
Ilia Zedguinidze watched from the sidelines as his team put in a poor performance, going down 24-12.
The match in Sydney, their final outing at the World Cup, came just four days after they had played South Africa.
"I'm very disappointed with the result," Zedguinidze said. "After the game against South Africa we did not recuperate enough."
In stark contrast, their south American opponents had had 13 days to prepare for the battle of the Pool C minnows.
That extra time showed with Georgia unable to match their heroics against the Springboks in a lacklustre display.
All their points came from the boot, with second-half substitute Merab Kvirikashvili landing three penalties to keep his team in the hunt.
However, in the final stages Uruguay's extra strength and experience told and they crossed for a match-winning try minutes from time.
Despite four defeats from their four pool matches, Zedguinidze was keen to look on the bright side of his country's first World Cup campaign.
"Playing in the World Cup was an excellent experience," he added.
"The Georgian team really grew up and match after match we did better."
Zara Kassachvili, vice president of the Georgian federation, echoed his captain's sentiments.
Kassachvili described it as a "great day" for Georgian rugby and is expecting many more in the future, including when his country is invited to join an expanded Six Nations.
"Georgia is here. Georgia will be here tomorrow. Okay, we are not satisfied with this result but we need time. A couple of years ago nobody knew Georgia. Now people know that we play rugby," he said.
"It was great to have one month to play four games. If we need to have the rugby we need more competition and this is the priority.
"We need more work and more experience, so Georgia needs this competition [Six Nations] and why not? We need experience. We are a baby."
