I've been playing the "Command and Conquer First Decade" game pack for over a month now. In the past I played through C&C 1 as GDI and RA 1 as the Allies, but never played the "evil" faction or tried C&C Tiberian Sun or RA 2. Heard they were great and boy where people right.
I went back and played both campaigns for C&C 1 and RA 1. Sadly I didn't finish the NOD campaign as one of the missions is impossible. Keep in mind I love RTS and C&C so I tried it a dozen times and can't finish. Red Alert was easier with the soviets than the allies I found since you have less, but stronger units.
I'll never forget C&C Tiberian Sun. It's probably equal to me as the best RTS of all time arguing with Starcraft and Warcraft 3. Tiberian Sun is just as great as the original, but with more units, awesomely detailed graphics and sound, but two unexpected things that stand out. First of all the detailed graphics, ambient music, and the post-apocalyptic setting (world transformed and dying from tiberium) blows my mind. I love looking over the maps. Second are the missions. In all the RTS I've ever played never have I had a great variety of missions that are unique. In other RTS the missions are either "make your base" or "command an elite squad" while you also "remove the enemy base" or "capture this structure". Tiberium Sun both blow the lid off of those missions (Warcraft 3 also has awesome missions, but that's another thread). I'll NEVER forget the mission from Tiberium Sun where you have to quell the civilan riot (GDI) or the mission where you have to retrieve part of the tacitus in a remote area of the world that's supposed to be completely devoid of native inhabitants and only populated with mutated lifeforms (also a GDI mission).
I'm now playing the Soviet campaign for RA 2. I really like the game for all the right reasons (detailed graphics, unique setting, good voice acting, skirmishg, etc.), but there is one serious flaw. The Allies GI is way imbalanced in being too powerful. Sure he's the weakest unit, but he's so cheap you can build many more. When you take into account the increased stats they get from deploying and the fast rate they gain combat experience you can not only beat much more advanced units with a small squad, but easily mass them due to their small size and short build time. It made the campaign very easy to win as the Allies, but I don't think I'll dare try RA 2 in multiplayer with such easy exploits.
Sincerely,
