If I find myself interested enough in this game I'll buy it and then use a pirated version instead.

That makes perfect sense especially for expensive hyped games by big companies that need to cover their expenses on day 1. I'm just wondering though: wouldn't it be a much better idea for a smaller or indie company, that can't afford fancy marketing campaigns, to invest into something that will steadily gain support from 'word of mouth' (or its equivalent for internet forums) that would assure steady sales for an extensive time period?
