Okay:
-Advance Wars: Days of Ruin may be the black sheep of its franchise (in terms of tone and setting), but it's still a good game, and IMO, the #2 Advance Wars game
-Command and Conquer: Tiberium Wars is the best CnC game, and Red Alert 3 is the best Red Alert game in the sub-series
-Diablo III is the best Diablo game
-Doom 3 is the best Doom game. Doom 2016 is average at best.
-Golden Sun: Dark Dawn is a good game, just not as good as its predecessors
-Half-Life 2 isn't that great. It's got great elements, but too many frustrating ones as well.
-Halo 5 is a good game, better than Halo 2 and way, WAY better than Halo 4 (and ODST for that matter...then again every Halo game I've played is better than ODST, so meh)
-Heroes of the Storm = best MOBA
-The Legend of Zelda: A Link to the Past is overrated, especially when compared to A Link Between Worlds
-Majora's Mask is a good game, but overrated (I know there was a period in time when MM was arguably underrated, but similar to what I've observed with FF7, the pendulum seems to have swung too far the other way)
-Metroid: Fusion is the best Metroid game (that I've played) - still better than Super Metroid (I'd argue that Zero Mission is also better than Super Metroid, but it's a tight race)
-Other M is a very flawed game, but not the monstrosity that people make it out to be. It's still far more palatable than Hunters
-Resident Evil 5 is a good game. Not as good as RE4, but still good, and better than some 'traditional' RE games (e.g. Code: Veronica and Zero).
-On that note, RE3>RE2
-The Sonic the Hedgehog series gets too much flak. On that note, Adventure 1/2 are still the best 3D games that I've played in the series.
-The Legend of Spyro sub-series doesn't get enough attention - while fun, it's unfairly overshadowed by the original series.
-StarCraft II>StarCraft I
-Star Fox Adventures>Star Fox Command (may be an atypical Star Fox game, but at least it's actually fun to play)
-The original Star Wars Battlefront games aren't that great (they were fun, sure, but I don't think they deserve to be on the pedestal so many put them on)
-Aliens: Colonial Marines is a good game
-Another World is overrated (I can appreciate what it's trying to do, I just don't think it does it that well)
Maybe I could think of others, but meh.
