Again my game making came to a halt from being addicted to the game "Heroes of Newerth" It's the proper made game of DOTA from a WC3 mod map. It's completely awesome. (If you have it and wanna play, you're welcome to play with me. I'm "Eggy55555") Playing recently with the type of community this game holds really brings up a lot of game making things to watch out for.
There is an argument called "Playing to Win" vs "Cheap Tactics". What this is, is using cheap tactics within the game to win that people frown upon. In HON you can sneak into their base and kill their towers before creeps get there. In FPS games it's known as camping or in fighting games you keep pressing one quick attack over and over. So should you do it? The answer is YES.
The reason is, people say you're the bad player for using these cheap tactics. However this is a flawed way of thinking, THEY are actually the bad players for not coming up with ways to counter these. If you go to a gaming tournament they will use every trick and tactic to win whether it's cheap or not. The more you play the game, the more you come up with counter tactics to these cheap moves. It's as simple as that.
Is he camping? Throw some grenades around the corner next time. Is he backdooring? Keep a teleport on you at all times. Is he spamming the same button over and over? Find an attack that can counter his or block it. People that whine about these things are locked in their of set of rules that they think everyone else should follow.
People won't understand this unless they reach a higher level of gaming. The only game I consider myself a complete PRO at would be Halo 3, and after playing so long, all the cheap tactics people say are cheap and unfair I actually love when people use because I have counters to them that actually make it even easier for me. I even come across counters to my counters and I have to come up with counters to that, and the list goes on.
Bottom line is - Before you say something is cheap, try and improve and learn to beat it first.
This is not to be confused with "Cheating" Cheating is using things outside the game to hack it or completely change things which is of course illegal and not fair.
