They don't threaten shit for me, there are plenty of PS360 games coming out lately. The problem is that Nintendo stopped going 50/50 on gamer and nongamer games and went whole hog for nongamer games. I bought 2 Wii games in 2008 - Smash and Mario Kart. One was actually good. Everything since then has been nongame bullshit until now, Punch Out, which I might not want if I owned one of its other iterations.
You are right about N64 and GCN being shit as far as new properties, but at least they still released games.
But yes, I should stop being disappointed with Wii because "Nintendo knows where the money is." That really helps me as a consumer.
Like Segata, I was gung ho for Wii right through 2007. I ignored stuff like Wii Play because I was getting Mario, Metroid, a little Battalion Wars in there, etc. That all dried up a year and a half ago and I don't use my Wii anymore. Why shouldn't I be frustrated with this $250 waste of space?
btw, people give plenty of shit to Sunshine, NSMB, TP, PH, etc. Galaxy is above it because it actually has a creative spark. People can be disappointed in Punch Out's meager roster without being afraid of Nintendo's market dominance. Maybe they just yearn for the times when a year long wait on a Nintendo console would at least produce a Perfect Dark or a Majora's Mask.
