I think the reason I can’t get excited about games anymore is that there’s nothing new. When I first played Command & Conquer, I’d never played anything like it. Same for Civ 2 and Rollercoaster Tycoon. Those games kept me up late for months. Now a game comes out and it’s “yet another ____.” It may be the best of its type ever produced, but the fundamental gameplay is something I’ve already seen and gotten bored of.
I think the only cure is to find games that are different. Recently I’ve been spending a lot more time on my GBA than PC gaming. The only PC game that really captured my attention for a prolonged period was Stronghold, because it appealed to my desire to build impregnable defenses in RTS’s. But even that wore off before I’d finished the campaign. (Of course, the sudden spike in difficulty had something to do with it too.)
I get excited by the games that aren’t in the spotlight. Evil Genius, Battlefield Command, Kings of War and Allies and Axis are games at the top of my list. So little information, so little hype, how can you not get a lil’ giddy?
