First I'd like to say to the OP that XCOM has several difficulty levels. 'Normal' is supposedly quite easy, though I haven't played it myself - and there is an even easier setting. The infamous hardcore mode is also an optional setting not suggested for new players. So the difficulty in itself shouldn't be a reason to skip XCOM.
Firaxis and Microprose have a tradition of including diffulty settings that are supposed to be almost impossible to beat, but they put in a lot of easier settings to.
I get bored by games that don't challenge me in some way. Difficulty isn't the only way to make a good challenge, but an otherwise good game can be completely ruined if it is too easy. Poorly designed difficulty can be just as bad and unchallenging though.
