If they didn't get a deal from Microsoft, the game would have likely received less funding, maybe not enough money to put it up to the standard of the first title. I guess it's a matter of perspective.
SE would be really stupid if that were the case.
Of the games they own, TR was easily one of the best selling. The only negative to it was a slow start and it didn't make back its money until later. They could probably have done with a marketing assist back then to drive early sales. However, the sequel is a shoe-in. They can budget for a likely 4 million sales. They could spend just as much as they spent on the first TR, having made that back in profits on the game, and be comfortable they'd be far lower risk than the last TR because there's >6 million TR buyers and the game reviewed extremely well and spread by word of mouth, which means sales were based on the quality of the game and not the quality of the marketing.
Just Googled this:
http://www.eurogamer.net/articles/2...arly-double-its-3-4-million-first-month-sales
"The company thought its Lara Croft reboot could sell at least 5-6 million units in four weeks - "
That raises questions about the management and forecasting. Considering the long-term 6.5 million sales of the game represent the
highest ever of any iteration of the franchise, wanting that much in the first month is plain crazy.
Maybe they budgeted for 6 million early sales, 10 million long term, and it was too expensive in the end? Maybe now they're looking at 2 million early sales and some marketing and financial help will help cover the cost of targeting a six-million seller?
It's probably time we moved more attention on to the SE side of this situation.
Edit: If we factor in the 'action adventure library' aspect, MS want a third-person cinematic adventure which they currently don't have (as Spencer explains). Meanwhile, TR would butt heads with UC4. A delay for PS4 probably wouldn't hurt TR on that platform, and it'd enrich XB1's library, so the choice seems mutually beneficial. The only real downside was fan flak and how it was handled.
