2007 Alien Syndrome was a good game for Sega. Was born 1985 in Oregon & grew up with Nintendo Mario since maybe 1989 and later started playing Sega Sonic games too. I've played X Box & Sony Playstation & computer games & Atari. But my three favorites are, first, Nintendo, second, Sega, and third, Sony. 4th might be Microsoft. I'm a fan of many games. Snowboarding games are very fun. Also, fighting, shooting, basketball, and RPG games too.

First favorite from your list above is Alien Syndrome. Second is Mech Warrior.
You sound like a well rounded gamer.
Was addicted to SNES Sim City in 1997. Was not always so balanced.
Was playing a lot of Tony Hawk around 2005 or so.
