That guy also played this game then. Fine let me do you one better as I’ve got more than 140 characters:
Aggression is rewarded by raising your attitude meter and if you get it to max you’ll have a limited window to perform a special move. If you manage to land one, go for a pin immediately after and it’s basically guaranteed. So your high level strat is build attitude, get special off and pin.
Great so only one part there is unclear. How, specifically, do you build attitude? 3 things. Attacks, grapples, taunts.
I’ll cover taunts first since they’re easiest. Taunt without being interrupted and you get some attitude. I tended to use these when I needed that last little bit to push from almost full to full but afaict they work the same all the time.
Strikes and grapples can both be countered but differently, so try to mix up what you go for or your opponent will be able to predict what you’re going for and counter.
Strikes come in 2 flavors, standing and running. Those running ones are partially why you picked a fast person, also because walking away from someone is a decent way of dodging a grapple or strike. I usually tried to find a character with a fast running attack and a fast stationary attack and just use that.
Countering attacks: there’s this thing where you puff out your chest (I think it’s bound to B but I’ve not played this in 10-15 years so this is high level) for a second, and if any attacks come at this time they basically fizzle and you’re open to a quick counter attack so use this and don’t attack if they’re puffing their chest.
Grapples come in 2 flavors as well strong and weak. the strong ones take a second to land as the guy kinda does a doubletake with his arms. IIRC counters to these occur as the grapple is landing and basically swat the grab attempt away, again leaving you open to counterattack. If you already have the grab you can do a move and there’s basically nothing they can do about it, it’s too late for them at that point.
Maybe I’ll fire up an emulator to refresh my skills and actually give real advice. I’m beginning to mix it up with the other N64 wrestling game, no mercy, in my head. Anyway the advice above is applicable but not as super pro as I thought after having read it once.
