I would say that nature of projects in the Middle East is more interesting than in the other parts of the world, because there are lot of strategy projects where you would be able to develop new things. Since there is ofthen the case that no pre-data or no-market is valuable before you would be able to work on new concepts and create smth new completelt from the scratch using "green field" approach which I find really cool. However, on the other hand, if you develop new things they cannot be perfect from the first side. Therefor the quality of work and the requirements are considerably lower than on the established markets in Europe or in the US. So sometimes you might face an obstacle during the exit options that your experience in the Middle East is not transferable to Europe or US, because these markets have already very developed environment and don't need basic skills which you have developed in the ME.
Nevertheless, it's a very interesting and very stip learning curve, I have spent 4 years in Europe and then 2 years in the Middle Eats, so I can compare two markets pretty well. If you need further insights, drop me a line and I'm happy to share my experience with you and give you some advices.
