My review is based on the retail release: The game itself back in it's original release was brand new and fresh in the stealth genre. It was amazing, to use the enviroment with its lightning and background noise. The graphics were good for the time and the soundtrack was also very well done. The GoG-Version delivers you the mission pack, which adds more and good levels to the game. It's awesome to see them here, because I had to buy an used retail-version of the levels over amazon. Back in January 2009 the Complete Pack offered only Splinter Cell 1 till 4, without the missions pack. But buying the old mini-addon is not everything. I had to update (or downgrade) Splinter Cell 1 for compatibility with the mission pack. I downloaded back in 2009 the "SplinterCell13DVD.zip", which was not easy to find on the old UbiSoft-Forums. Who knows if this patch package is still online, I saved it on my harddrive. After applying this patch, you have to install the mission pack. Nice to see GoG providing it and spare us with all the patching. More I cannot say about the compability of the GoG version (because I own retail), but I thing it should run very well on modern OS. I played the retail version on Win Vista and it worked well. I give 4 stars, because the Sequels Splinter Cell 2 (Pandora Tomorrow) and 3 (Chaos Theory) are even better. On technical and completeness side I would give 5 stars (if there are no issues compared to the DVDs on Win Vista and upwards).
