If you like combat, play Jagged Alliance 2 - the BEST, BAR NONE turn-based combat.
Silent Storm has better combat than JA2. It's not the most balanced game out of there, so modding it is recommended though. It lacks strategic aspects JA had but the combat itself is a direct evolution of what you could see in JA2, like somebody would look at that game and say - well guys, today we have much better technology, I think we can do something like that but better. So they've did Silent Storm.
You can fite my
objectively superior opinion as much as you want but you and me know that I've won.
OP - you see, the list is imho. good but there are obvious flaws everywhere. For example storyfaggotry. Planescape sure has wonderful story, tons of C&C but FUCK this gay game - people play non-combat routes in it just to avoid terrible combat. It is a huge flaw and game like that doesn't deserve #1 on any list.
Arcanum on #5 is also misunderstanding, objectively speaking, same goes for Bloodlines at #6.
System Shock is somehow RPG but Thief isn't.
Alpha Protocol is the most glaring shitty pick possible. The game deserves to be in 60's on that list for great dialogue and C&C but if everything else sucked(core gameplay) or was mediocre at best(story) it's not something fit for place #29.
And so on and so on.
A lot of those deserve a place on that list but not that high. Others(Mount and Blade - for variety of reasons, but you'd have to make another thread for it) deserve much higher one.
The reason for it is the fact that it was a result of a poll. Poll made by people with very various tastes. Poll which result was distorted by hordes of Obsidrones, retardo children who's first RPG wasn't Oblivion, no, they're not some kind of casuals, their first RPG was glorious, inclined KotOR and Morrowind
and so on and so on.
I'd say that lurking helps with understanding the list. You'll get to know what kind of people visit this site which will help you filter that list for games you'll want to play.
