This game is a prequel, where Batman is still viewed as an unknown quantity. Its Christmas Eve and and entire rogues gallery is out to collect a bounty placed on Batman's head by Black Mask. If you enjoyed any of the other games in the Arkham series, you'll be right at home with this. Gotham is presented as an open world crimefighting playground rich with goons to beat up and crimes to solve. The atmosphere is rich and the voice acting is stellar, with Roger Craig Smith playing a younger version of the late, great Kevin Conroy's Batman.
While the character faces are just...hideous, I always loved Oblivion for it's world! Its beautiful, and looks so alive. This really pushes the immersion to the point you really feel like you've been whisked away into a fantasy realm.
To put it simply, New Vegas is a Wild West tale of revenge set in the 1950s version of what the post apocalyptic future would look like. It vastly improves what they tried to do with Fallout 3, by just doing it all so much better, and with all of the DLC content included you've got lots to do. And you get to do it your way. Heck, the game will even custom build a fully narrated ending for you, completely dependent on how you choose to end the main story, who you meet along the way and how you interact with them.
Doom 64 was largely forgotten, because it arrived when games like Quake, Goldeneye and Turok were eating up all of the attention. Doom 64, simply put, is the true Doom 3. Everything you loved about Doom 1 and 2 are ratcheted up an extra notch here. The monsters are meaner, the atmosphere is scarier, the weapons feel punchier, and the level design is more devious than ever. Not simple key hunts, some levels require you to radically alter their geometry to compete. Secret levels are actually important as they contain powerups to a weapon that makes beating the final boss, a less painful endeavor. Doom 64 looks fantastic on modern systems, and you can even turn of that ugly melted texture blur found in the original version of the game! There are quality of life improvements like modern controls, and a set of "lost" levels that continue the story. All this for five bucks.
